Access database users may encounter certain error messages while accessing the MS Access database. Most of these error messages identify the cause of the MS Access database corruption. An effective way to repair the database is by using an inbuilt utility known as Compact and Repair. However, if this utility fails to repair and restore the database, then you need to recover and restore it from the latest backup. If you have not created any backup or the backup has been corrupted, then you need to repair the table by using effective Access Recovery Software.

As a practical scenario, a user is performing certain operations on the MS Access table and the computer shuts down due to power outage. When database user restarts the system, he discovers that the table has been corrupted. To repair the table, he uses the inbuilt “Compact and Repair” utility. However, the inbuilt utility is unable to repair the table and shows the below error message:

“Microsoft Office Access was unable to completely repair the ‘|’ table and deleted some Memo, OLE Object, or Hyperlink field values. To recover the data, restore from your backup copy of the database. Note that the data in the deleted field may have been damaged by a bad sector on your hard disk. For more information on checking your disk’s surface, files, and folders for errors, search the Windows Help index for ‘checking for disk errors’”

The above error message mainly appears because of the bad sectors in the hard drive. As the error message suggests, you need to recover lost data from the backup copy of affected database. The error message also shows that the some of the Memo, Object Linking and Embedding (OLE) object have been deleted in the repair process. To prevent the occurrence of the above error message, you should always repair the table by using advanced Access Repair application. However, in the above scenarios, if you have not maintained any backup, then you need to use a powerful Access Database Repair tool. This software is specifically designed application that incorporates effective scanning methods to provide comprehensive Access Database Repair. With interactive, intuitive and highly graphical user interface, this utility can be easily deployed by a normal user.

Stellar Phoenix access recovery is the foremost Access Recovery utility that provides absolute and systematic database recovery. It recovers fields like Auto number, Hyperlink, Yes/No and OLE object field in tables. This read only recovery utility supports Access 2007, 2003, XP (2002) and 2000. It is compatible with Windows Vista, XP, 2003, 2000 and NT.

 

NTP servers (Network Time Protocol) are devices that can synchronise a computer network to an authoritative UTC time source. UTC (Coordinated Universal Time) is a global time scale used throughout the world and provided by atomic clocks.

NTP servers can receive UTC time either across the Internet from places such as nist.gov or windows.time. However, it must be noted that Internet based timing references can’t be authenticated and may leave a network vulnerable to malicious attacks such as DDoS (Distributed Denial of Service - normally caused by malware that floods a server with traffic) that blocks access.

Fortunately dedicated NTP servers can receive an authenticated timing reference through either the GPS network (Global Positioning system) or specialist long wave radio broadcasts normally emitted from a national physics laboratory. Some NTP servers can receive both signals and even use them at the same time to ensure better accuracy.

GPS NTP servers are extremely easy to install as most time server manufacturers supply easy-to-use software with their devices.

Normally a GPS NTP server consists of a rack mount NTP time server, A GPS receiver and IEC Power Cables.

For installation first locate a suitable area for the rack mount NTP Time Server in the rack mount enclosure, bearing in mind you will need to run a cable from this location preferably to the roof of the building or by a window if you are using GPS.

Locate an area to mount the GPS antenna, the ideal place would be the roof of the building with a 180 degree view of the sky but bear in mind that you will need to keep the GPS antenna close to the power source on the roof of the building. Things to avoid are air conditioning units and power distribution units as these will cause electrical interference.

The cable should be run from the rackmount enclosure to the selected mounting position leaving some slack cable in case you need to move the unit at a later date! Note: The maximum workable cable length for a GPS time server is 1000 meters (1km).

The four core cable is attached to the rear of the rackmount NTP Time Server using a small junction box. The standard wiring for the GPS antenna is as follows:

1 – Brown, 2 – Orange, 3 – Yellow, 4 – Green, 5 – Blue, 6 – White

With both units wired first power the GPS antenna then power up the rackmount server. Some time servers gave a small LCD screen at the front where on screen diagnostics are displayed. In most cases the unit will synchronise within 15 minutes, the delay is due to the GPS antenna locating and synchronising to satellites.

The configuration of the NTP Time Server can be achieved over the network using an internet browser.

Many smaller businesses tend to have a limited understanding of the difference between peer to peer networking and making the leap to a proper client server network. Over the last few months, Microsoft has upgraded its operating systems and applications for servers, notably Windows Server 2008, SQL Server 2008 and brining out Service Pack 1 for Exchange Server 2007. In doing so, they have brought out a very powerful, co-ordinated product offering for organisations from small businesses to the largest corporation.

This can provide some of the advantages in time saving and efficiency to small businesses that have, hitherto, only been accessible to larger organisations.

Windows Server 2008

When you put a server in place, you need an operating system specifically designed to operate in a client sever environment, hence Windows Server 2008.

One of the main advantages that this gives, is in security. The new technologies in Windows Server 2008 help prevent unauthorized connections to your networks, servers, data, and user accounts. Any computer that attempts to access you network runs into Network Access Protection (NAP) which makes sure that they comply with your organization’s security policy. As importantly, BitLocker Drive Encryption gives greater protection against data theft in the event that server hardware is lost or stolen, as well as providing more secure data deletion when your servers are eventually decommissioned.

The Server Manager provides a single console that simplifies server set up , configuration and management as well as allowing administrators to automate routine tasks over multiple servers.

If your business relies on remote workers, has satellite shops or offices, or needs to provide access to company data for sales representatives, Terminal Services RemoteApp provides this. Authorised staff can easily access standard Windows-based programs from anywhere by running them on a terminal server instead of directly on a client computer - without the need for a complicated virtual private network (VPN).

Sharepoint, which comes with Windows Server 2008, provides the ability to share applications like Excel spreadsheets, which can be accessed and updated by staff, whether in the office or remotely. It provides a focal point for company and or team activity which can really boost productivity by having one set of documents that every one can access and update directly.

Exchange Server 2007 SP1

MIcrosofts Exchange Server 2007 is another invaluable aid to keeping everyone up to date and coordinated. It provides e-mail messaging, calendar organisation and unified messaging. It provides built in protection against spam and malware attacks with an integrated, IP based block-and-allow list based on sender reputation and are automatically updated. Administrators can also create additional IP allow-or-deny lists if necessary.

The Calendar Attendant helps to reduce conflicting appointments by limiting calendar items (request, declines, accepts) in the inbox to the latest version. It also shows meeting requests as tentative on individual calendars until all the people invited to attend the meeting reply.

In addition to Exchange Management Shell, the Public Folder Management Console lets administrators quickly manage public folders, including creation, deletion, and the replication configuration of individual folders.

SQL Server 2008

Of course, one of the great strengths, and main reasons for having a proper server based network is providing access to a common database for a number of concurrent users. Whether this is to control information , such as stock movements or provide information for customers from an e-commerce website, SQL Server 2008 delivers integrated services that let you query, search, synchronize, report and analyze data. Furthermore, as it is stored in an organisation’s server and accessed by desktops and mobile devices, it can be simultaneously updated and queried without having to manage replication issues.

The reporting engine in SQL Server 2008 Reporting Services allows you to integrate and report on data from a number of functions within the company. Large and complex reports can be produced in various formats, including list, chart, table, and matrix. They can incorporate data from Oracle, SQL Server, DB2 and many other sources and then you can preview, print and publish the reports with the integral report builder. You can also export it easily to Office 2007 products such as Excel to manipulate it into “what if” scenarios or Word for presentations and reports.

Conclusion

Every business has its own, individual, problems and what would be a critical benefit for one company, would be irrelevant to another, so it is not possible to cover all the features and benefits that might be relevant to all businesses. Suffice it to say, that, if you run a small to medium sized business, it would be worth examining the advantages that you might experience by moving to a proper client server network.
