mapped drive I/O error

I am running two W2K SP 4 Terminal Servers with MF XP SP1.
I have an application that makes extensive use of mapped
drives. The application frequently hangs when usage is
high, and I see the following in the event log:

Application Error : The instruction at "0x019a10f5"
referenced memory at "0x019a5004". The required data was
not placed into memory because of an I/O error status
of "0xc00000c4".

Q272582 discusses this, but indicates this was fixed in
SP3. I am running SP4 and having the issue. I checked
the versions of Mrxsmb.sys and Rdbss.sys, and they are
later than the versions indicated in the article.

Anyone else experiencing this?

Maybe try turning off RFCB caching...

As one of the articles says, have you tried to move the
files to a local disk (if possible) to see if the problem
still occurs?
