Endpoint Protection

Hello friends,

MY SEPM is not taking updates from 13th of thios month, i re-started the services on my server. now i found a new problem, i am not able to logon to that server.
when i enter username and password and click on logon, nothing is happening. as picture shows.
please help me on this issue......

reboot your server, you should be able to log in ,
the service might be in stopped state however you wont find that in services.msc
try doing iisrest from run, check if that helps you to log in 

If above suggestion not helps paste/attach the scm-server-0.log with is present in Program Files \Symantec\Symantec Endpoint Protection Manager\tomcat\logs

hi Rafeeq,
i re-started the IISrsset. but no luck.
last time i tested re-start i was worked fine.
this time i want the solution with out re-start the server.

thanks for the help.

Can you let us know the version of SEPM and the OS installed.

Ensure that the required  Symantec services are running.

Try a repair on the Symantec endpoint protection manager and then try to login.

As per the screenshot the error could be due to either IIS or Tomcat.

There are two common causes for this issue:

The %TMP% and %TEMP% system variables do not match. This can be checked using SET TEMP and SET TMP in a command prompt.
The permissions for the Users group is incorrect for the TEMP folder underneath %SYSTEMROOT%. By default, a Windows installation should allow specific permissions to the Users group. If these permissions are insufficient or not present then PHP is unable to create its session files, and cannot display graphics or proceed any further than the login page in the SEPM console. This can be corrected by assigning the appropriate permissions to the Users group. In the Permissions Entry dialog for the Users group, ensure that Traverse Folder/Execute File, Create Files/Write Data and Create Folders/Append Data are checked.

your iis would have stopped accepting connections, you can see that in the logs under, 
 C:\WINDOWS\system32\LogFiles
you will see connection dropped messages, the problem is with IIS and not with SEP ( if you find any errors in the logs)
As you mentioned earlier, restart wil fix the issue.
running a repair, will re-register the sepm module with IIS and would restart all the worker process of IIS, let us know the results.

Go to add remove program and Run a Repair for SEPM
