HTTP 500 - Error in a Call Manager Publisher Server
I have a CCM cluster 4.2(3) - the cluster was working fine but since some days ago when I try to open the administration page https://<ipaddress>/ccmadmin, I get a HTTP 500 - Internal server error and the page is not displayed. The IIS, the World Wide Web Publishing Service, and the other Cisco Call Manager Services are running. Other Cisco CCM pages like the DNA or the BARS pages are working fine. I restarted the server but it didn't work.
What can I do to restore the administration of the cluster?
Re: HTTP 500 - Error in a Call Manager Publisher Server
that usually are bad news, in some cases a simple iisreset clears it but if other pages are available the issue might be that the web pages for the ccmadmin site got corrupted, open the iismanager on the server and verify the pages are in there.
my experience with those cases is that usually it ended up in a rebuilt or an upgrade so the files were installed again.
i'd really recommend to raise a TAC so they can verify the iisadmin status and maybe look at some iis logs to determine if there is anything else you could try
