Sytze, this sounds like it might be the oplocks problem where an application runs perfectly fine when only one user is logged in but slows down when more than one logs in.
Here are my notes on switching this off. http://oplocks.net/how-to-disable-win32 Multiuser system speed 1. Set OPLocks off for increased speed in multiuser systems HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MRXSmb\Parameters\ set OplocksDisabled = 1 OplocksDisabled REG_DWORD 0 or 1 Default: 0 (not disabled) 2. HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters SharingViolationRetries REG_DWORD 0?1000 attempts Default: 5 Determines the maximum number of times the Server service attempts a file operation when the file system responds with a sharing violation error. If a client requests more attempts that the value of this entry allows, the Server service returns an error. This value entry applies to open, rename, and delete operations. Note Windows NT does not add this value to the Registry. You can add it by editing the Registry or by using a program that edits the Registry. SharingViolationDelay REG_DWORD 0?1000 milliseconds Default: 200 Determines the time interval between repeated requests for a file operation when the file system responds with a sharing violation error. This value entry applies to open, rename, and delete operations. Decreasing this value (requesting more frequently) increases network traffic. However, increasing this value (requesting less frequently) might delay users unnecesarily. Note Windows NT does not add this value to the Registry. You can add it by editing the Registry or by using a program that edits the Registry. Frank.
