Steve,

I still don't have a clear answer for my similar situation.  We have a 
6.5++ Windows app running on a 10/100 network.  The database resides on the 
domain controller, a Windows 2000 Server with Active Directory.

I have come to believe that the major issue we face is having the database 
sitting on this box.  A domain controller in a WAN installation has a lot 
of communicating to do with the other servers and other locations.  The 
server is not stressed, but it seems that the file i/o services get reduced 
in priority to other tasks on the box.  We see not only delays in connects, 
we see failed connects, and we see a lot of "Waiting for access to required 
resource" messages as well as "Updating database information - this 
operation cannot be interrupted."

Granted I am not a W2k Server expert; far from it.  But my common sense 
tells me that something is locking up file 1.

Early on we were seeing situations where a desktop PC would insert a row, 
but a thin client on Metaframe would not be able to see that row for up to 
10 minutes.  Either the DC was not flushing its write cache to disk, or it 
was not refreshing the read cache, or both, or the Metaframe server was not 
refreshing its cache, or something.  I have no other explanation for how it 
could take ten minutes to see a new row from a different machine.

Recently at this location we replaced a patch cable between the DC and the 
switch, and matters have improved.  The cable tests to within spec, but its 
removal eliminated all sorts of collisions.  But we still see the messages 
that appear to be file 1 contention, just not as many.

We are working on our next major installation, and here I have included a 
souped-up database server for nothing more than holding the database 
files.  Database I/O will not have to compete with anything other than 
network I/O.  This installation goes live 1/19/02; I'll report our findings 
in early February.
