Registry Problem WTS 2008

Hi everybody,

I have a strange problem:

I have a Server2008 WTS environment. Sometimes it happens that I get

messages like this:

{Lost Delayed-Write Data} The system was attempting to transfer file data

from Buffers to \Device\LanmanRedirector. The write operation failed, and

only some of the data may have been written to the file

(in German)

Message ID 50

Last Word C000020C

(Yes, I have posted that message before and got no answer...)

Now, I have performed some tests. They showed that some registry keys seem

to disappear.

Am I correct that every user on a WTS should have a set of keys under

HKEY_USERS?

When the error occurs, it seems like one or several of these sets are not

available anymore.

Has anybody experienced a similar problem yet?

Thanks for your time.

Ole
