Here's NAI's answer on this: Dear Customer,
The following is a status update regarding the STORE.EXE termination issue on the Microsoft Exchange 2000 platform. Information circulated by Microsoft internally has indicated that McAfee updates for the latest virus DAT files were the cause of the STORE.EXE termination. There is no correlation between the current McAfee DAT files and the STORE.EXE termination issue. Root cause analysis done at McAfee indicates the issue is with a message that has a very long sender name (>511 characters). This issue was first seen late last year and was resolved in HotFix 2 for McAfee GroupShield 5.2 for Microsoft Exchange 2000. All customers who have seen this issue would be running a GroupShield service version of less than 5.20.677.0. This can be verified through the GroupShield Exchange Manager | configuration | properties | version tab. We have posted Hotfix 2 for McAfee GroupShield Exchange 5.2 and this is currently available on our support service portal at: http://mysupport.nai.com Users should login to the PrimeSupport KnowledgeCenter Service Portal and navigate to: Hotfix & Patch List for McAfee Security Products | GroupShield HotFixes |NAI28995:"HotFix 2 for GroupShield 5.2 for Exchange 2000" There is also a TechNote article posted in the NAI mysupport.com Knowledge Base: reference nai31469.

Customers should be aware that the latest DAT file from NAI requires NAI's Hotfix 2 (HF2) prior to applying the latest DAT file. If the customer applies the DAT file without applying the Hotfix from NAI first, their Exchange Stores may terminate. All versions of Exchange 2000 are potentially at risk although Microsoft has not seen issues outside of North America at this time. Resolution / Call to Action * Ensure you have the latest patches (HF2) from NAI prior to applying the latest DAT file from NAI. Determining if Hotfix 2 is installed On the version tab of the NAI console, the last three digits should be 677. If not, you are not running HF2. Contacts for NAI NAI has asked that we funnel all customers through the following two people at this time. * The US contact for NAI is Brad Gable ( <mailto:[EMAIL PROTECTED]> mailto:[EMAIL PROTECTED]) * The Europe/Middle East/Africa contact for NAI is Kevin Gudgion ( <mailto:[EMAIL PROTECTED]> mailto:[EMAIL PROTECTED]) If you are already experiencing the problem, please contact NAI or Microsoft PSS immediately.
