Time to time we are unable to connect to the server through RDP once windows firewall disabled by Domain GPO and an hour later it works again. If we enable the windows firewall in GPO it's working fine, the only thing we found the following error:
The Terminal Server security layer detected an error in the protocol stream and has disconnected the client. Client IP: x.x.x.x
Microsoft Product: Windows Operating System; Version: 6.1.7600.16385; Event ID: 56; Event Source: TermDD;
OS: Windows Server 2008 Standard SP2 and 2008 R2 SP1
Client OS: Windows 7
Could you please someone help to fix this issue?
Thanks, Parthasarathi.B
