SYMPTOMS
When a news client logs on to an Exchange Server computer that acts as a news server, and then issues a &quot;STAT&quot; command, the Exchange Server information store service may stop unexpectedly because an access violation occurs. The stack dump is similar to the following:

FramePtr RetAddr   Param1   Param2   Param3   Function Name 1143f984 78021646  1143f99c 011315b7 1143fdf0 0x7801031c 1143f9bc 006172b5  1143f9e0 00000400 01131598 0x78021646 1143fdd4 00613d86  01131598 00613df0 14c4f608 STORE!NNTPCON::HrSendStatusResponse+0x3d(...) 1143fecc 00616633  00000015 00000001 14c4bfd8 STORE!NNTPCON::EcArticle+0x356 1143fef8 006162f4  0111af68 0000000c 0000000c STORE!NNTPCON::EcOnCmd+0x332



CAUSE
The issue can occur if the information store sends a message in response to the client that issued the STAT command. Because the related message has a percent sign in the message ID, the information store incorrectly processes the character as a type field character when the response message is composed, which results in an access violation.



RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
