SYMPTOMS
========

When a news client logs on to an Exchange Server computer that acts as a news
server, and then issues a "STAT" 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.
