Here is the syntax to capture a memory dump using adplus (part of the debugging tools). FYI if you need to capture a ultra large w3wp process, you will need to increase the ping timeout inside IIS so the dump doesn’t fail. IIS will detect a ping failure, and recycle before the memory dump has finished writing to disk. I’ve used this since IIS DebugDiag doesn’t work on 64 bit of windows server 2008.

Thanks for the info.

What’s the difference between using adplus vs. windows task manager’s Process “Create Dump File”?
(taskmgr > select process > right click > create dump file)?

The only difference is adplus allows you to chose the output folder. By default, using task manager puts in the c:usersusernameappdata.. folder. This is another option. That is all. 🙂
