We have an sbs 2003 R2 server that has quickbooks premier 2006 installed on it. It's been running fine for a couple years. Users can't get into quickbooks today - they get an error that the file can't be opened and the error code is -6108,-105.
I try connecting via RWW to the server. I can log in remotely, it accepts my password but when I try to connect to the server I get 'connectivity to the remote computer cannot be established....'. RWW on that server has been working fine for a long time also. I can RWW to desktops no problem.
Microsoft says something else might be using port 4125 (but I can get to the server to sign in, so it's not completely messed up). I stopped the MAD.exe service and still no luck.
Nothing in the event log about any errors.
