We migrated a client from SBS2003 to SBS2008 a couple of years ago, they have just now come to us saying that since the server was installed thier custom built Hire program runs very slowly on the PC's, each PC has a mapped drive to the EXE which sits on the server drive, they run it at the PC and it takes about 8 seconds to open the dB on the server.
They have fault found the network, the PC's and the Server to hell and back and can't work out whats causing the problem.
They can transfer larges files very very fast from server to client, they can open the Hire dB in excel on the client very fast.
They have removed all antivirus with no results.
Appears that SBS2008 is slowing the transfer of data down when the EXE is opened from the network.
All clients are XP Pro 32bit and all worked very fast on old SBS2003 32bit.
Only change was to SBS2008 64bit and a new Dell T310 server with H700 Raid ctrl.
The hardware seems to perform very well for all other tasks.
Any ideas of what to try next?
