Have recently built a new Windows 2012 R2 sever on the network and installed Remote Desktop Services. When users connect to the 2012 Terminal Server, their mapped drives show a red cross. They are still able to access the network drive though and when they do, the red cross does not disappear.
Have spent countless hours researching this problem on the internet but still haven't found a fix. Have tried the following
- Instead of mapping drives using GPO, have used a logon .VBS script
- Deleted TS user profile
- ran command net config server /autodisconnect:-1
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Service\lanmanworkstation\parameters
Value: KeepConn
Data type : REG_DWORD
Value : 65535
- enabled the GPO - Always wait for the network at computer startup and logon
Read the following articles. Couldn't do much as these articles don't apply to Windows 2012

Observations
- The first user that connects to the Terminal Server session gets the drives mapped fine however subsequent users get the red cross in their drive mappings
Am at my wits end! Have even tried rebuilding the server from scratch but the problem still exists. I don't have any problems on another server Windows 2003 TS with the same GPO being applied to the users.
