Have you tried disjoining and rejoining the RDS server to the domain? Is the servers computer account in AD? Have the users got the correct rights to connect to the RDS server? Is the server physical or virtual? Have you ensured the server is connected to the network?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Check system logs first, then application logs for error. Run GPO simulation wizard on this machine from  your DC and check what all GPO's are getting applied on this machine. Sometime OS corruption also causes this issue. You can run sfc /scannow in admin mode and check again.

Does this effect a specific server or all servers?

it affect 2 servers with windows 2012 servers.
GPO simulation wizard was successful.
again when this problem happened before some time, i removed its network cable from switch & reconnected. it started working.

in most cases this is a dns issue. are there any events related to the DNS service on either the DC or on the RDP server?
are the users connecting with stored credentials? have you tried getting them to connect manually in case their stored credentials are the issue?

can you log onto the RDP server *while the issue is occurring* using a local account so you can confirm if it can see/ping the DNS/DC servers?

what happens if you log into the system using the domainname\username vs the drop down?
Put the Domain info into the host file and give it another shot.. see if that helps
does group policy have the setting checked to wait for the network before allowing logon?

what happens if you log into the system using the domainname\username vs the drop down?...... results r same.
Put the Domain info into the host file and give it another shot.. see if that helps. done but did not work.
does group policy have the setting checked to wait for the network before allowing logon? there is no group policy implemented.

Did you try an nslookup at all to confirm the domain resolves?

do you have more than one DNS set on the TS's NIC?
0
Rob GMicrosoft Systems EngineerCommented:
How many NIC's are on this server?
Are they teamed?
Make sure you only have one gateway on one NIC if there are more then one.

What is the server connected to?
Is the DC local, no firewall in the network, or separate VLANS?
Is the DC a full DC or a RODC?

You mentioned the DC is a 2k8 server?
What is the domain level?

is the DNS hosted off that server or an external source?
Is there an AV?
What is the AV?
Have you tried without the AV running?

The error you listed...
Is there an event ID that occurs with it?
Does this stop you from logging in, or does this error appear, and still allow login, (Cached)?

Are these servers physical or VM's?
if they are VM's what are they, hyper V or ESXI?

sorry i could not update status since was down with health issue. anyway, problem got resolved, it helped by adding entry of domain controller  in host file of windows 2012 server.
