Hi,

we are trying to change service account using k2 setup manager wizard.

in our envr, there're two servers. we stopped the  k2 service on the 1st server,  no txn is to the 2nd server, but k2 service is not stopped on the 2nd server. 

upon the setup manager finished, we found the newly added app pool (integrated mode) is stopped in in IIS application pools, we can mannually start it up, but upon refresh, it become stopped again.  But the k2 service is able to startup using the new service account.  howerver all our website using the service account are not able to load.

furthermore we discovered we cannot even create a new app pool  in the IIS application pools manually. we hit the error " there are no more endpoints available from the endpoint mapper. (Exception from HRESULT:0x800706D9)". but prior to run the setup mgr, we are able to. the other server is also able to create new app pool manually.

we encountered this issue when we tried to change service account (both acc are in the same domain 1). whileas our k2 servers are in another domain 2, there are 1 way forest trust from domain 2 to domain 1. sufficient permission is added to service ac. 

any clue of the issue above issue and how to resolve it? thanks in adv.
