SYMPTOMS
========
When a Network News Transfer Protocol (NNTP) client logs on to an Exchange
Server computer that is configured as an NNTP server and the client issues a
"LAST" or "NEXT" command, the information store service may stop unexpectedly
because an access violation occurs. The Dr.Watson log or the User.dmp file
contains a stack dump that is similar to the following:
FramePtr RetAddr Param1 Param2 Param3 Function Name

CAUSE
=====
The issue can occur if the information store sends a message in response to the
client that issued the LAST or NEXT 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
==========
