SAP/FourthShift DCOM Problem (workstation)

Client running SQL version of SAP/FourthShift v 8.5 SP02 PL00. Server W2003 AD, had a crash. Did a rebuild, and all came back up using the MS Disk for the rebuild. Can connect and run the SAP/FS without a problem, but getting this error when running backflush:

Can run backflush without an issue from the server console, but no clients (all running XP SP2) can run backflush. SAP Thinks it may be a DCOM issue from the client connecting to the server. All users are in the DCOM group in AD. All users have access to the registration directory on the W2003 server.Start Free Trial
