SYMPTOMS

This error is followed by multiple Warning 90 messages that list the transactions that were not processed following the error.
CAUSE
This error occurs intermittently and is related to cached file closes under control of the Microsoft Windows NT operating system.
For additional information on other causes of Fatal 7 errors, please see the following article in the Microsoft Knowledge Base:
134228 Err Msg: Fatal [ 7] Error Renaming File
RESOLUTION
The following registry entry has been effective in eliminating the occurrence of the above errors:
HKey_Local_Machine\System\CurrentControlSet\Services\LanmanWorkstation
\Parameters
CacheFileTimeout=0
WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.
To add this entry on the Windows NT Server where the postoffice resides:
- Click Add Value on the Edit menu (not the Add key).
- Type the Value Name of CacheFileTimeout.
- Change the data type to REG_DWORD (default is REG_SZ).
- Click the OK button. You will be prompted for the Data.
- Type 0, and click the OK button.
- Exit the Registry editor; shutdown and restart the Microsoft Windows NT computer.
NOTE: This value specifies the maximum times that a file will be left in the cache after the application has closed the file. In this case, the parameter was set so that the closed files will not be cached.
MORE INFORMATION
CacheFileTimeout option is not directly related to Opportunistic locking. Even with the CacheFileTimeout value set to 0, the redirector may still hold up the close of the file. The opportunistic locking has not been shown to be a cause of this problem and may be left enabled.
For additional information on the CacheFileTimeout parameter, please see the following articles in the Microsoft Knowledge Base:
