We just migrated the last of our mailboxes from our exchange 2007 server to our exchange 2010 server, the exchange 2007 server is now completely decommissioned and offline.
We are running server 2008 and exchange 2010 sp1.
Multiple times every week we receive the following error on our exchange 2010 server.
Watson report about to be sent to dw20.exe
TIME OF EVENT: 2/17/2012 6:08:42 PM
EVENT LOG: Application
EVENT SOURCE: MSExchange Common
EVENT ID: 4999
DESCRIPTION: Watson report about to be sent for process id: 3012, with parameters: E12, c-RTL-AMD64, 14.01.0218.015, M.E.RpcClientAccess.Service, M.E.RpcClientAccess.Handler, M.E.R.H.RopHandler.Logon, System.InvalidOperationException, 41bd, 14.01.0218.012.
I have been researching this, but haven't found much in the way of a clear explanation as to what it is.
Bar the error in the event log, I don't see it actually having a negative effect.
Any help or advice is welcome!
Thank you in advance.

Thank you for the replies.
I am just awaiting change control approval from the Operations Manager,
most likely I will have it by this evening and will update to SP2.
Will let you know in the morning.
Thursday, March 01, 2012 7:45 PMHi Owen. I just noticed I'm having these on one of my CAS servers as well, so I'm interested to hear whether SP2 RU1 fixes it. I'm on SP2 now.

Did SP2 RU1 helped?
We started to have these issues today.

very sorry for the delay in getting back to you, we had to wait a month to get approval to impliment sp2 ru1.
It is in place now and we are still receiving the error.
Any further suggestions would be most welcome?

just to keep this alive for anyone having the same issue.
I logged a support call with microsoft about a month ago for this, they have yet to resolve the error.
I can tell you it is the process w3wp.exe (MSExchangeECPAppPool) crashing intermittently that is causing the error, but no reason as to why yet.
Will keep updating as Microsoft continue to work on the problem.
On a side note, this doesn't seem to be actually having any kind of impact that we are aware of.

ok so the latest is, it looks as if SCOM was causing the error.
We put SCOM monitoring for the exchange server into maintenance mode and we didnt get the error for a week (it ususally come sin once or twice a day). Reenabled the monitoring and the error came in again.
Looking deeper it seems to be the ECP monitoring in particular causing the problem.
The exchange guys in microsoft want to increase the interval of scanning, but the SCOM guys say this is not possible, so we have disabled the ECP monitoring for the moment to see if the error comes in again.
Hopefully this helps somebody out.
I'll update again next week when I have monitored the server.

The issue persists, Microsoft support have asked me to install RU 3 to resolve the issue.
Installed this last night, so will see over the next few days.

RU 3 has resolved the issue.
