We are experiencing intermittent disconnects between our VPN users and their exchange mailboxes

Using Windows Exchange 2003. Users who connect to our network from their XP workstations, via VPN, are receiving messages when in Outlook that tells them that Outlook must be on line, when they click on the TO line or hit the address book. This is intermittent. If they exit out and try it again it works. Minutes later the issue re-appears.

I am not sure of your Outlook version, basically what I am trying to say is that remove and and readd the Outlook Address Book, set the Contacts as the Default Book
Hope this helps
Thanks

After more scrutiny we observed (thru wireshark) that packets heading back to the client from the DC do not consistently make it back to the client. When this occurs it appears to correlate with the error we are experiencing. Generally this is when the user clicks on the TO or address bar (which it would check the DC for). We have a network team trying to identify this idosyncracy. I will post their findings after they complete their tests.
