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 &quot;LAST&quot; or &quot;NEXT&quot; 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 1143f984 78021646  1143f99c 011315b7 1143fdf0 0x7801031c 1143f9bc 006172b5  1143f9e0 00000400 01131598 0x78021646 1143fdd4 00613d86  01131598 00613df0 14c4f608 STORE!NNTPCON::HrSendStatusResponse 1143fecc 00616633  00000015 00000001 14c4bfd8 STORE!NNTPCON::EcLast 1143fef8 006162f4  0111af68 0000000c 0000000c STORE!NNTPCON::EcOnCmd 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 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.
