I'd like to pose another question while this topic is semi-fresh...
I am currently using a box running v5.6u (server only mode-behind the firewall!) at my company to centralize all of the Quickbook Pro files. The 'local' network users have had no problems accessing and using these files, but when we started connecting a user at a remote office via a secure IPSEC VPN-freeswan connection (via 2 separate boxes running v5.6u in server/gateway mode--1 at each location, of course), that's when the problems started.
First of all, when the remote office user ends his session in Quickbooks Pro (the latest version), the .qbw file becomes inaccessible to all of the local users. So far, the only quick solution that has worked to un-lock the files is to reboot the server hosting the files. Not the best option. Is the drive mapped at the remote location? Yes. Is the user logging in to the session as "multi-user"? Yes. What gives!?
Also, the connection at the remote office is extremely sloooow. I've tried to explain to management that this is because an internet vpn connection is not going to have near the throughput of data that a 10/100 connection will. I've demonstrated this with ping stats, 84ms from the remote connection, .06ms from the local. How can I improve this without getting a hyper-expensive connection setup? The local office has a static 768k T1 and the remote location has an ASDSL connection w/static IP(512k-I think).
In any case, I've been handed the thankless job of "fixing" these problems. Any help/guidance/clues?
