Did you trywith the ip address of the SEPM machine, instead of name ( or  vice-versa)?

Also, if you log in on local SEPM console, do you also face the  same  issue?

Check console timeout settings(Admin--> Servers-->local site properties)..... 

or you can remove java and reinstall and see

You have this problem on a other computer or only yours ?

You could try this:

• Uninstall all Java Version and the SEPM console on your Computer
• Check of UAC an Windows Firewal as Disabled
• Empty Cache and Temporary File on Internet Explorer
• Try to Install the Java version is Attach on this post
• connect on your SEPM in IE with the 9090 port and install SEPM console.

Had problems similar to this. I just uninstalled the SEPM console and reinstalled it. Not the best solution though. But it did work. I'm betting on the fact that the server will install evrything I need to run the virtual on the desktop I'm using.

On the SEPM server restart the "Symantec Endpoint Protection Manager" service, then try again.

Hi Curropar,

Can you go to IIS, click on the positive sign for symantec webserver, right click on reporting and click  browse.

It will ask you for a username and password type your sepm username and password (leave domain blank) and then click login

see if that shows you the sepm console or if not what is the error you get.

You can also try the stpes on the following URL.
