Can you share the server model?

Thanks for your reply.  I've followed the instructions and can now get to the login screen but when I enter my username and password, and click on submit, I'm taken back to the login screen.

The server is a PowerEdge R510.

Can you try with different browser or launch OMSA remotely from a different machine on the network and see whether it works

Hello,

Happy New Year. Sorry for the long delay in replying but things have been manic in the past month.

On a server running Windows 2008 using IE I can not only login to OMSA but can am not asked for any credentials. If on that server, I change the url to point towards a 2008 R2 server, I am asked to enter credentials and it fails to recognise them. There is no firewall either hardware or software between the two servers.

Hello,

that's strange, which credentials are you using to login? Which is the error?

Thanks

Marco

Ok, please can you try to restart the Server Adminstrator services?

Here how to do this:

Hello Marco,

I'm using the same credentials that I use to logon to the servers.  There is no error message.  After I click on Submit, I get "Verifying Credentials" and am then taken back to the login screen.

I've restarted the server and checked to ensure that all four DSM services have started, and the problem still exists.

Was having this issue and successfully logged in with the FQDN and using Chrome for the browser
