The computer may stop responding after you install Trend Micro OfficeScan 8 on a computer that is running Microsoft Windows 2000 Server or Windows Server 2003

After you install Trend Micro OfficeScan 8 on a computer that is running Microsoft Windows 2000 Server or Windows Server 2003, the computer may gradually become less responsive. Eventually, the computer may stop responding.

This problem occurs because a leak occurs in the system non-paged memory pool. Non-paged kernel mode memory usage may increase until the memory is exhausted. If you analyze the non-paged pool tags, you see that the Ddk pool tag is the largest consumer of the non-paged pool. The Ddk pool tag is the default tag for driver-allocated memory.
