I am running WG 10.0 on a Vista HP SP1 workstation attached to Server 2003.

Any time I try to access a data file on the server I get Error 94.

If I copy the data file to my Vista workstation and access it, everything is okay.

 I can access the files on the server using my XP workstations.

Here's one thing to be aware of.  It may not be what's blocking you today, but it's been a factor during our testing. 

Vista and Win2K8 changed the protocols associated with remotely accessing file systems.  On the Vista box, go to the Administrative Tools and launch the Local Security Policy editor.  Expand "Local Policies" and then select "Security Options".  Scan down the list for an item called "Network Security: LAN Manager Authentication Level".

On Vista and Win2K8, this is set to "NTLMv2 Responses Only" by default.  However this will prevent these Vista/Win2K8 boxes from being able to interact with Win2K, Win2K3 or WinXP since these older Windows platforms do not understand or participate in the newer NTLMv2 protocols.

The full explaination is too much to include in this note, but you can read about the details here: http://support.microsoft.com/kb/823659.  You'll find the full details under ithe item labeled "10. Network security: Lan Manager authentication level"

 Another cause of the status 94 with the workgroup engine and remote drives is when running as a service.  The default user the service uses is LocalSystem which does not have access to mapped drives. Either change the Workgroup to run as an application or change the user the service uses to a user that has rights to the remote drive and use UNC in the application. 

 Mirtheil,

I did install the WG as an application.  I have solved my problem by entering the name of the shared location on my server into the "Working Directory" field in the "Configure Local Engine" section of Control Center.  Everything now is working properly.

Thanks
