Installing ACCPAC Plus on Microsoft NT

Article ID: accp750

The information in this article applies to the ACCPAC Plus for DOS Windowing System Manager.

Summary

This article discusses steps you should take before using Windows NT Server or Windows NT Workstation to run ACCPAC Plus software.

Install Windowing System Manager 6.5

Windows NT may return an incorrect file size to one of the ACCPAC Plus sorting routines used in many posting functions, causing data corruption.

Windowing System Manager 6.5 includes a workaround to prevent this problem occurring.

Turn Off Opportunistic Locking

Opportunistic Locking utilizes record caching on each workstation on the NT Network. However, the cached records are not properly maintained and updated. Therefore, cached records may contain incorrect data. This leads to unbalanced transactions in ACCPAC Plus. To turn off Opportunistic Locking:

1. From the Run dialog box, enter "Regedt32".
2. Open the Parameters directory (\Hkey_Local_Machine\System\CurrentControlSet\Services\LanManServer\Parameters).
3. Select Edit, then Add Values from the menu bar.
4. Type "EnableOplocks" in the Value Name field
5. Change the data type to Reg_Dword. Then click OK.
6. In the DWORD editor, enter "0" in the Data field. Then click OK, accepting the default Radix.
7. Reboot the server.

Note that you should turn off Opportunistic Locking on both the NT Server and all NT Workstations.

Do Not Update System Files during Windowing System Manager Installation

When installing the Windowing System manager on a Windows NT workstation or server answer "No" when prompted to automatically update system files.

After installation, manually enter the FILES=250 command in the CONFIG.NT file. (The CONFIG.NT file resides in the \WINNT\SYSTEM32 subdirectory).

Is the Files=250 Command Required?

ACCPAC Plus requires the Files=250 command in all Windows environments. Installation automatically places the command in the CONFIG.SYS for Windows 3.1x and Windows 95.

In Windows NT environments however, you should add the command to the CONFIG.NT file manually. Although Windows NT v4.0 tries to build a configuration file including commands from both the CONFIG.SYS and the CONFIG.NT files, we suggest that you enter the command in the CONFIG.NT file (usually found in the /WINNT/SYSTEM32 subdirectory).
