Drive letters for virtual disks under XP

NTFSD
1

Hi,

I have a virtual disk device that creates itself a drive letter using
IoCreateSymbolicLink. On NT and W2K, explorer will show the drive, but
on XP it won’t. It is accessible from a command prompt though.

I seem to remember this being mentioned before, but I can’t find any
suggestions for a solution (if there is one). Any ideas?

Thanks
Shaun

Check MSDN. There is an article.

I don’t suppose you remember the article number or some keywords
from the article, do you?

Thanks

Use mount point manager on w2k and xp. See mountmgr.h and mountdev.h and xp
ddk.

It isn’t an option for some kind of drivers. We discussed this topic in th
ntdev list; search the archives. My workaround was to use
BroadcastSystemMessage() for device arrival with DBTF_NET flag. I wasn’t
able to find KB article which Jamey mentioned. Maybe there is a better
solution.
