Hello and good day!
First of all - sorry for the long post! Hopefully the detail will save time overall. Any help at all would be much appreciated. Thank you in advance!
Issue:
I cannot get the NPS role installed on a brand new Server 2012 domain controller. The error that system manager keeps giving me is; "The operation cannot be completed, because the server that you specified requires a restart." After this error system manager will continue to run but it will not allow me to do anything at all. It is unable to look up any status information for my other installed roles (the status switches from green to red on all installed roles) and I am unable to install any other roles until after reboot. Rebooting seems to fix system manager, but if I try to install NPS again I get the same error and system manager gets hosed again.
The kicker is that I did have NPS installed but was having RADIUS issues, so I removed the role with the intention of re-adding it. That is when I started running into this problem.
History:
- Freshly installed Windows Server 2012 (maybe a week old?), fully patched.
- The server in question is running as a domain controller with no FSMO roles, a DHCP server and a DNS server. All of which seem to be functioning fine. The server also has a DPM agent installed.
- Today I successfully installed the NPS role in hopes of configuring RADIUS for my wireless access point. After installing NPS I could not seem to get the radius server to listen/bind on port 1812. I tried a variety of steps to solve this but nothing worked. I didn't do anything out of the ordinary in this troubleshooting, like registry editing or anything. I tried binding port 1812 in the NPS properties by using <serverip>:1812. I also disabled IPV6 on the adapter temporarily. Much to my surprise after changing the port settings back to normal for NPS and attempting to restart the service, it would not restart. It kept failing with 0x80072740... Error 0x80072740 Only one usage of each socket address (protocol/network address/port) is normally permitted..
- At this point I became annoyed (I know, I know, I should never let that happen. Whoops!) and so I decided to start over because the 0x error wasn't lending me a straightforward solution. Thus, I removed the NPS role, which appeared to complete successfully and without error.
- Once rebooted I started having the issue in system manager outlined above... A quick check in services showed me that the NPS service was still trying to run.What? I thought I had just removed it? So I set the startup type to disabled and rebooted once more. This time the service was gone after I rebooted but the problem with re-installing the role remained. Eeek.
- I have been crawling through the event log to find anything relevant but I have yet to find anything.
** Update **
After attempting to install NPS the event log recorded EVENT ID 7045:
A service was installed in the system.
Service Name: Network Policy Server
Service File Name: %SystemRoot%\System32\svchost.exe -k netsvcs
Service Type: user mode service
Service Start Type: auto start
Followed by EVENT ID 7036:
The Network Policy Server service entered the stopped state.
Followed by EVENT ID 7023:
The Network Policy Server service terminated with the following error:
Only one usage of each socket address (protocol/network address/port) is normally permitted.
Any ideas are welcome at this point. Thanks again.
