Event ID 3019 - MRxSmb

A very common event error that appears on many workstations and servers is this:

Event Type: Warning
Event Source: MRxSmb
Event Category: None
Event ID: 3019
Date: 13/11/2009
Time: 8:27:32 AM
User: N/A
Computer: ALOE
Description:
The redirector failed to determine the connection type.



This error can be ignored. It occurs whenever a network drive is mapped, and a user goes and tries to map the same network drive again. For example if you have a logon script that maps the drive when a user logs in, then next time they login it tries to remap the drives again, it will generate this error for each failed drive mapping.
