Multiple SRS's or Not?

Here's the deal (don't ask why we do the things we do, we don't know either).  Our primary organization consists of 10 (5.5 sp4) sites.  One site's specific purpose is to connect an E2K server into our Org.  This has been up and running for a couple years.  This site is homed by a 5.5 server and an E2k (let's call it "Mail1") server was installed into that site.  So far so good.  We have recently added another E2k (call it "Mail2") server into this site.  Everything continues to work on Mail1, however replication on Mail2 does not.  The one SRS now points only to Mail1.   What was making me question if I need an additional SRS or disable the service on Mail2 was the following errors (see below) this server experiences upon boot.  Even though the error indicates that the EDB is corrupt, I don't believe that is true.   I actually moved my mailbox onto Mail2 for a week and mail traversed normally.   The only issues I experienced were with components that need to be replicated.
 

Any help would be greatly appreciated.

No, only have one SRS in a site; not even sure it will let you do 2. So, the SRS is currently not started? That means no replication is happening at all; the SRS is the intermediary between the 5.5 dir and AD. When did this start?

Has the 5.5 service account password changed in the E2K site, at any time?

wait; why is the SRS on MAIL2? Did you add it to the correct 5.5 site?

In answer to the first response this Q article says you can have two.  http://support.microsoft.com/kb/255285

Second, yes the pwd has changed.

Third, From what I understand SRS is installed by default and yes it currently resides in the correct site.

Yes you're right, though I've never considered having a second SRS, that's just trouble. Only reason to have one is if the first one isn't working or the database got deleted/corrupted, and couldn't be recovered. I think maybe the changing of the service account password in 5.5 broke the replication. Personally, I'd just stop the SRS on the new server, and see if things are still working between the 5.5 server and your new MAIL2. Any other replication errors?

I agree, One SRS should be sufficient.  I leaned towards the password thing but everything is working fine between all the original servers.  However replication is not occurring to Mail2.  Also, I disabled the SRS service on Mail2 and applied the post SP3 update rollout for E2k.  I have also rebooted Mail2 again  to see if that helps.   I'll watch it over night and update in the morning.

Thanks

you're welcome :)

Make sure your ADC version is up to date, service pack for Exchange won't automatically update it. You might, just for safety's sake, turn up diagnostics logging on the ADC, clear the applog, and force a full replication during off-peak hours, and see if you get any serious replication errors on MAIL1. Just to be sure.

Well first thing I did this morning was check to see if replication occurred to Mail2.  Much to my surprise I saw the public folders and the OAB replica was there. It's gonna be a GOOD Holiday weekend.  

This Q article addresses some of what I was seeing -  http://support.microsoft.com/default.aspx?scid=kb;en-us;811212.  That is what led me to apply the post SP3 rollup.

Just to recap a couple things for posterity:

1.   Only need one SRS under normal circumstances
2.   Password change was not relevant - problem existed prior to change
3.   Disabled SRS on Mail2 - POSSIBLE FIX
4.   Installed post SP3 rollup - POSSIBLE FIX
5.   ADC downloaded the latest and greatest when server was built a month ago.

 Moved My mailbox back to Mail2 and everything is working as expected.

PS. Just as a test, I initiated replicating a public folder from one of the 5.5 sites to Mail2 before I started typing this reply and by the time I was finished Mail2 has its very own copy.  NOTE: our equipment is not really that fast, I'm just a very  s l o w  t y p e r - lol

Thanks Again!

Ok, so things are working, just keep that SRS disabled on MAIL2. Let me know how everything else goes....
