I assume you mean logging into FMS and not Windows?
A hub? Eeeek! We still have schools that use them, so can't moan too much.
Where does your "SIMS FMS Module" icon point to?
C:\SIMS\FMSLOAD.EXE "C:\SIMS\Finance.exe"
Or...
S:\SIMS\FMSLOAD.EXE "S:\SIMS\Finance.exe"
The latter will mean you are dragging the "Finance.exe" program across the network.
Far better when installing FMS to have the program files local.
Re-install FMS on the workstation (using a 6.82 or above CD) and when you reach the screen "Network Installation Components", select the top two options, then on the next screen "Where is the SIMS Directory?", type C:\SIMS
(CD's prior to 6.82 will over-write S:\SIMS\Setups\FMSApplicationSetup.exe and its signature file, so make a copy first!)
If it is still slow, read the tail end of FinanceC.pdf and look at the page 55 (as shown on the bottom of the page, not in the Adovbe window!)
