Many many event id 9175 on exchange 2003 server

[zacca]

Hi there,

Exchange2003sp1 FE + BE servers both running on w2k3 servers.

Since this sunday found that a lot of event 9175 in applicatin log, all of them are the same as follows:
source: MSExchangeSA
Category: MAPI Session
Type: Error
EventID: 9175
User: N/A
Computer: EXCHANGE
Description: The MAPI call 'OpenMsgStore' failed with the following error: The attempt to log on to the MS Exchange Server computer has failed. The MAPI provider failed. MS Exchange Information Store ID No: 8004011d-0512-00000000

In between those tons of 9175 events, there are a few single entry of event id 8197 as follows:
source: MSExchangeFBPublish
Category: General
Type: Error
EventID: 8197
User: N/A
Computer: EXCHANGE
Description: Error initializing session for virtual machine EXCHANGE. The error number is 0x8004011d. Make sure MS Exchange Store is running.

The 9175 event is logged almost 1 entry per minute. I'm pretty sure that information store, system attendant, mta stacks are all running on both FE & BE servers, as all users can send/receive emails without problem.

Just wondering what's the cause of those 9175 event & how to fix it?

Million thanks!

Hi Andy,

My case is rather tricky, checked that all related MS exchange services are started, logon as local system.

Now I observed that system attendant service is started, but from ESM, backend sever's mailbox store|logons, there is no sign of system attendant, while on my frontend server's mailbox store|logons, there is system attendant logged on.

I just don't know why in my BE server, the system attendant logon was gone. Any idea?

Million thanks!

Check the following, it would appear to be your exact error.

Hi Andy,

The event id is 9175 but the description is not the same:
The MAPI call 'OpenMsgStore' failed with the following error:
The attempt to log on to the Microsoft Exchange Server computer has failed.
The MAPI provider failed.
Microsoft Exchange Server Information Store
ID no: 8004011d-0512-00000000

But 1 thing you're right, when I tried to manually force rebuild the offline addrbook, it didn't work & said
"MAPI or unspecified service provider.
ID no:00000000-0000-00000000
ID no:c1050000
Exchange System Manager"

Sorry to keep on bugging you but do you have any further suggestion? Many thanks!

Nope, I'm all out of good idea, time to invest in a call to PSS.
