Dear Experts, we could not use remote Desktop service into a Win server 2008 R2, it said that "Your credential did not work"; some steps were performed but could not help:
1. Open all Firewall profiles, disable Antivirus
2. Changing password
3. Create a new local user and add to Remote Desktop Group
4. Change remote port
5. Restart RDP service
6. Allow remote desktop service
Any idea please?
