Object self locked. Can't work anymore with the Portal !!

Hello,

We have installed on Win 2000 the NW04 Portal environment. Everything was OK so far.

But yesterday, we made an upgrade with the latest windows update available and with the Stack 09 of the Portal J2EE Engine in order to implement the LDAP correctly. Since then, we got problems when accessing to any objects of the Portal (EP 6.0 SP 3 Stack7).

The object is self locking and we can't modify it, the object is in Read-Only Mode.

We do not find any information about this on the SapNet neither on SDN. Did you already encountered such a situation ? Is there a parameter that need to be change after the Windows update or J2EE Engine Upgrade? Could you help us ?

Thank you for your answer.

Marc.
