When you use web console for SCOM 2012 RC you will face a problem that every 30 minutes it will sign out automatically to avoid this problem you have to modify this setting in the web.config file for the web console
Steps:
1- locate the web.config file by opening IIS then right click then explore for operation manager web portal
2- open the Web.config file
3- you will find this
<connection autoSignIn=”true” autoSignOutInterval=”30″>
<session encryptionKey=”SessionEncryptionKey”>
<overrideTicket encryptionKey=”OverrideTicketEncryptionKey”/>
</session>
<managementServer name=”localhost”/>
</connection>
and find also
<connection> <session encryptionKey="SessionEncryptionKey"> <overrideTicket encryptionKey="OverrideTicketEncryptionKey> </session> <managementServer name="localhost"/> </connection>
4- Change it to be like that
<connection autoSignIn=”true” autoSignOutInterval=”0″>
<session encryptionKey=”SessionEncryptionKey”>
<overrideTicket encryptionKey=”OverrideTicketEncryptionKey”/>
</session>
<managementServer name=”localhost”/>
</connection>
and
<connection autoSignOutInterval="0"> <session encryptionKey="SessionEncryptionKey"> <overrideTicket encryptionKey="OverrideTicketEncryptionKey> </session> <managementServer name="localhost"/> </connection>
5- restart IIS to take effect.
