We're having lots of problems with our MAS90. Clients are receiving random file not found errors. We're trying to rebuild the key files for each module and they all seem to rebuild just fine with exception to the Accounts Receivable module. The Accounts Receivable rebuild gets stuck at AR_Audit and will sit overnight without moving on to the next section. We have run checkdisk several times, restarted the server, rebuilt sort files on all modules, ran sfc scan, and made sure MAS90 is up to date with all patches. Antivirus software is also disabled.
Also some additional information: The MAS90 server is running in a Hyper-V virtual machine running Windows 2012 Standard. There are also points and time where even when I try double-clicking the sage icon from the server it will take 5+ minutes to display the login prompt and another 5+ minutes after clicking login to show the MAS90 page. I don't see any other network problems when this happens (ping times are fine, no network disconnects, etc.)
What should my next steps be?
