The Exchange 2003 Sp1 mail server shows the following error in the
application log,

Event Type:     Error
Event Source:   POP3SVC
Event Category: General
Event ID:       1051

Unexpected error condition: call to function
resulted in error code 0x800cc801.

Microsoft knowledgebase article kb275291 suggests that the client is
trying to
use SSL. SSL is configured and its working fine.

Any idea why this error is getting generated ?

What about SSL? Is you Exch Server configured for POP3 and IMAP
clients to use those products over SSL? If not, you'll see those
errors and you can probably just ignore them if you do not require SSL
for IMAP and POP3 clients.

How can I generate a user friendly error message when validating XML against a schema?
Hello When validating xml against a schema, the most frequent error I get is something like "The 'FOO' attribute has an invalid value according to its data type. An error occurred at , (25, 913)". That error message is not very user friendly, so I'd like to extract the data in the failing node along with its parent node data, and show that to the user. Do you know a way to do this? I don't think there's any other information about the error position than the line number and position. Yes, line number and position is the only information that you have to...
