RPC_E_ACCESS_DENIED error (0x5) was thrown by the RPC Runtime
Posted on 2010-09-01
RPC over HTTP works only in 1 circumstance:
when using servername\administrator in stead of domainname\administrator.
When using other accounts we get rpc errors using the testexchangeconnectivity and the logonbox in Outlook 2007 keeps poping up.
Somehow the user gets resolved against the local SAM of the Exchange server. The exchange server is a member server. Total servers is 2, both running W2K8 64.
tcp6 disabled, auth method basic, rpc completely reinstalled, using exchange 2010 sp1, read almost every blog about the rcp over http issues.
Does anyone know what I am overlooking here?
PS also get security eventlog fail audits when trying to use a user mailbox in Outlook to connect via RPC/HTTP. Eventid is 4625: security ID: NULL SID ..etc etc
