Eddie,
While this really is off topic (it's more a VPN question than an ISA
question)......
We need more info on the database apps you're running and what you've done
to try and track down the problem... Is an Oracle/MS SQL type database or a
MS Access type database? If it's MS Access based, and you're running
queries on databases located on a remote file server, you need to remember
that Access does all query processing / report generation on the client
side. The client needs to access all the records in the database which can
take awhile on a slow link...
I've found that with things that require a lot of two way communication
(Access queries, Synching Outlook to an Exchange server, etc), network
latency over the VPN connection often times has much more to do with
apparent slowness than the actual speed of the connection... This is also
something to consider.....

I am having the following VPN through ISA performance issues and hope
someone can point me to the right direction.
ISA Enterprise install as firewall and during day time have around 80
firewall sessions and 60 web session, and everything seems to work fine from
inside out.
Coming from outside the firewall with vpn, my client outlook (on win2k)
works fine. Their web browsing works fine. Their generic network connection
works fine (connecting to a network drive, working with MS Office and saving
files through vpn to the server)
Working with some other databases application is un-predictable. Sometimes,
50% of the time works fine but the other 50% of the time will be so
un-reasonably slow that even refreshing a screen takes more than a minute.
But at the same time, Outlook and other web activities will be performing as
usual.
Any clue??
