We have a remote workstation with Quickbooks 2008 trying to attach to the company files on a WinSBS 2008 server. We're getting H202 errors now and I've used the QuickBooks Net Diagnostic Tool to find out what the problem is. The next step is figuring out how to resolve the problem because I'm not sure what it means.
Here is the text from the Diagnostic Log which contains the offending results:
20100126.03:05:38 UTC UNC Conversion for mapped drive is \\sbs01.dcla.local\data\QuickBooks\Company Data Files\DCLA, Inc..qbw

I don't know if something's not getting passed through the Cisco ASA5505 VPN or if I've got some DNS settings wrong on the server, or what.
