public folder store will not mount

[prha]

Hi,

I installed some critical windows update files on my exchange server, after the restart my public folder store will not mount. The private store is fine and up and running. I uninstalled all the updates, restarted and still no joy.
When I try to mount I get the error message "an internal processing error has occured, try restarting services" ID number c1041724.
I also get the error ID 9519 0x89a in event viewer.
I have searched around on these errors and there are quite a few differing solutions, ranging from permissions (I have checked all and they are OK) to corrupt DB.
I have run eseutil /mh and the shutdown was clean.
I am at the stage where I am choosing to run a soft/hard restore, or a repair.
I am under the impression that once I run a repair I can not run a restore?
Has anyone got any advice points I need to consider?
I was planning on running eseutil /d to defrag the off line store and then /p to repair?
Is this the way forward?
any advice appreciated.

Disk space?

C1041724 error occurs when you try to mount a database

You'll need plenty to do an offline defrag.

Hi,
Thanks for the response, checked this as well, as there was a message in event viewer saying that when it reaches 18gb it will dismount, but it's less than 1Gb.
Does it mean 18gb in total/public folder store and mailboxes? either way it s less than 18gb
thanks

18GB would be the total data stored in the pub.edb and pub.stm files combined.

I found this on the microsoft site. Although it hasn't fixed my problems, this is the cause..

I will contact Microsoft and find out what I can do, so far still can not mount the public store, can't restore from back up, can't recreate a new one and restore via .pst...
I'm at a loss...

I have read this on the Microsoft website but I can't decide what is trying to say my brain is fried from microsoft terminology:

This problem may occur if the Microsoft Exchange Information Store service experiences an ecAmbiguousAlias error when enumerating the groups and users that are assigned permissions to the store databases objects in Active Directory. The error occurs when a security identifier (SID) cannot be resolved to a single user. In this scenario, the SID is present in the security descriptor of the database object that will not mount. The SID cannot be resolved to a single user if one of the following conditions is true: • The SID is for a well-known user or group, and more than one domain exists in the forest. Therefore, duplicate objectSID objects are created.
• Two or more of the following objects have matching or conflicting values: • objectSID
• msExchMasterAccountSid
• sIDHistory
These three attributes must be unique within the forest.

WORKAROUND
To work around this problem, first check the permissions in the Exchange environment to make sure that no well-known accounts or groups have been defined to the permissions of the Exchange stores. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
243330 (

http://support.microsoft.com/kb/243330/)

Well-known security identifiers in Windows operating systems

Can someone please translate this to layman terms! Does this mean I need to remove all the users that are listed in the "well known accounts" from the permissions of the exchsrvr\mdbdata folder?

thanks

Microsoft have posted hot fix for this:

The hotfix ignores the well know SID's and lets you mount the store.
