SYMPTOMS
When you install Microsoft Exchange Server version 5.5 on a computer running the Korean version of Windows NT Server 4.0, the Microsoft Exchange Server Information Store may stop unexpectedly with a stack dump similar to the following:
FramePtr RetAddr Param1 Param2 Param3 Function Name
0e45f688 00433144 000004e4 0000001e 00000010 STORE!@EcFormatStandardStringProp@36+0x44

0ed8b338 0ed8b338 00000001 00000040 00000000 STORE!@EcRpc@16+0x49e
Also, when an English client attempts to open a message, the display name of the recipient may be corrupt.
CAUSE
The problem only occurs when the recipient's mailbox has a longer alias name in English than the display name in Korean. When an English client attempts to open a message whose recipient has a Korean display name, the Information Store attempts to perform a conversion between the English code page and the Korean code page, which always fails and returns a string of question marks. The Information Store will then use the simple display name, which is the same as the alias name; however, it passes the incorrect parameter of the string length to the function to allocate the memory for the simple display name, so that the new display name does not end with "/0." Following access to the new display name causes the Information Store to stop responding or corrupt the display name.
