Have a Server 2008 R2 Standard 64bit with remote desktop services, 32Gb RAM. We needed to increase RAM prior to upgrading network app. Installed 192 Gb RAM, showed 32 Gb usable.
We ran in place upgrade using DISM, completed successfully. Server showed all available memory, remote desktop working fine.
Following day, remote desktop user reported that they are unable to print. All installed printers failed to print. Restarted print spooler did not help. Installed a new printer, install completed but failed to print. After rebooting the server, users could no longer establish RDP connection, as if RDP was disabled.
I removed the print server and RDP roles and was able to rdp into server. Reinstalled the roles and RDP is now disabled again, still cannot print. I attempted to RDP to localhost, failed. Moreover, system now shows 192GB (4.00 GB usable).
System and Application logs are clean, as if everything is working fine.
Any help will be greatly appreciated.
