Fix: Remote Desktop Connection ‘ An Internal Error has Occurred’

Remote Desktop An Internal Error has Occurred

Many time we need to take remote to system connected in Network Domain. We take RDP through windows default Remote desktop tool(MSTC). After Entering Hostname/IP of System to connect, It freezes and Error-" Internal error Has Occurred " pop comes after few second. Many times, We restart system and it fix. But after few hours, It again come with same error.


As per my Experience Exact cause for the Error-" Internal error Has Occurred "is  due to group policy security implemented in organisation. I did all below setting to fix the issue. & once done all setting Never faced issue for  Internal Error.


1. RDP Security change in Local Group Policy
2. Terminal server Outstanding connection change

3. Group policy- Remote desktop security
4. Domain Rejoin


** Make sure all setting done with administrative account only**

1. RDP Security change in Local Group Policy

1.1 Edit group policy  Go to Run(Win+R) type gpedit.msc

Go to Computer configuration>Windows Component>Local Policies>Security Options>

System cryptography: Use FIPS complaint algorithms for encryption , hashing and signing

1.2 By Default is Disabled. If it is Enabled then Disabled  Or  it is Disabled then Enabled it

2. Terminal server Outstanding connection change

 You may workaround for this issue is to increase the maximum outstanding connections limit. On client it is 100 by default, while for server  it is 10000. The following DWORD registry key controls this value:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\
DWORD: MaxOutstandingConnections
VALUE: 10000

3. Group policy- Remote desktop security

Go to Run(Win+R) type gpedit.msc

Computer Configuration >> Administrative Templates >> Windows Components >> Remote Desktop Services >> Remote Desktop Session Host >> Security

Set   Require secure RPC Communication & Require USE SSL for RDP Connection to Not configure or disabled

In case already have setting Not configured then Enable to Require USE SSL for RDP Connection as RDP

 

4. Domain Rejoin

4.1 Go to Run(Win+R) type sysdm.cpl 

4.2 Under Computer name tab, domain, and workgroup settings, click Change settings.

4.3. Under member of select Work group and type any name as workgroup (ex-xyz) and click OK

4.4  Now it will ask for credential to unjoin. Now type any crendial or domain ID having Domain rejoin access.

4.5 Click OK, and then restart the computer

4.6 follow same process 3.1 and select domain (compnydomain.com) and join

 After  apply all above 4 steps Till time not found same issue.  Share your views  any issue for RDP.
