Could not login to PDMWorks Workgroup

"Could not login to PDMWorks Workgroup" is the message I gotwhen trying to login on Vault computer from other computer. When Itry to login from other computer with VaultAdmin it takes about 5to 10 min before anything happens. The rest of the message reads:"Please check that the vault computer name is correct and thatPDMWorks Server is running on that computer." The vault computername is correct and the PDMW Server is running on the othercomputer. On the vault computer everything is working. I havechecked everything on the network side and firewall settings.
Before I upgraded to PDMW 2007 SP3 I noticed that on the othercomputer that client version was on SP1 and Vault version was onSP0 whereas on the vault computer both was on SP0. I dont know howthe vault client got to SP1 because we did not update SW Exploreron that computer.

I have uninstalled PDMW Workgroup and SW Explorer SP3 on the vaultcomputer and reinstalled them to SP0 and on the other computeruninstalled SW Explorer SP3 and reinstalled SP0. No luck still notworking.

I hope someone can help me clarify this mistery because I have nothad any joy from my VAR regarding this problem.
When the client want his drawings he is not interested in listeningto you SW problems.
