Abysmal table open times on one workstation

One of my clients just bought a new workstation for one of their power users- Dell Dimension 8100 with a P4 1.3G, 256 MB RAM, Win2K Pro, VFP6 SP3.

After getting all the OS set up, and the applications installed, we notice that our VFP apps run _very_ slowly on that machine only. Form load times are measured in minutes, when normally they open in 1-2 seconds.

I opened VFP 6 and started testing the time that it takes to open files on the network, and found some very bizarre behavior. A 5K table in a dbc on the network drive takes 3-4 seconds to open, and a 60 MB free table opens instantly. Any table that is in a DBC takes a very long time to open, and all free tables open quickly.

Additionally, It takes about 1 minute to MODI FORM a moderately complex form with subclassed controls that opens in 2-3 seconds from other workstations, but USEing the scx file from the problem workstation opens it instantly.

The only rhyme or reason I can put to any of this is that it seems that opening a table (dbf or scx) that requires that VFP open one or more other tables upon using it causes the delay- using any 'free' table is quick.

Anybody ever run into this?
