SP4 modified the schema of the databases. You did make a backup before
upgrading to SP4, right?

> Hello all
>
> I have two Exchange 5.5 sites with one server in each site (Windows NT
> Server 4.0/sp6a, Exchange 5.5/sp3 on both servers). I am using Exchange
> behind Proxy 2.0 in one site, and in order to make inter-site
communication
> possible, I had to assign a fixed TCP port for the MTA (I am using port
> 6000). It was working fine, until I upgraded from sp3 to sp4. Since then,
> messages are stuck in the MTA queue, and I get error messages every 10
> minutes that say:
> "An RPC communications error occurred. Unable to bind over RPC. Locality
> Table (LTAB) index: 4, NT/MTA error code: 1753. Comms error 1753, Bind
error
> 0, Remote Server Name TOM [MAIN BASE 1 500 %10] (14)"
> I had this same problem in the first place (with Exchange sp3) before I
> assigned a static TCP port for the MTA (because of MS Proxy), and the
> solution was to assign this static port.
> Is there a way to fix this problem? And if not, can I revert back to sp3?
