SYMPTOMS
When you try to copy files from File Manager to a Novell Netware server over a 56KB link using Client or Gateway Service for Netware, the following error message appears:

Cannot complete the file copy operation.

No connection to remote computer.

If you run the NET USE command, the connecting and disconnecting network drives seems to work successfully. However, after disconnecting from a network drive, the connection list displays the drive as still being connected.



CAUSE
This problem occurs due to NWRDR not negotiating the right packet size.



WORKAROUND
To workaround to this problem, disable the Netware PBurst option on the Windows NT Advanced Server 3.1 computer. To disable PBurst, use the following procedure:

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.

 Start Registry Editor and go to the following subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \NwcWorkstation\Parameters

 From the Edit menu, choose Add Value. Enter the following value:

Value Name: MaxBurstSize

Data Type: REG_DWORD

Value: 0

 Exit Registry Editor and restart Windows NT.

NOTE: This procedure disables PBurst for all servers. There is no way to change this on individually on each server from the client computer. The default value of MaxBurstSize is 1 (enable).



STATUS
Microsoft has confirmed this to be a problem in Windows NT and Windows NT Advanced Server version 3.1. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
