Ask the Experts
Sr. Server Administrator
Are you mapping drives from the remote location? How exactly are you using the ts
I understand that the warning event 3019 appear when you using Remote
Desktop to the SBS machine. If I'm out of base, please feel free to let me

Usually, this event occurs when you map the same drive to the same share on
the same PC more than once. Please check whether this happens on your SBS
server when you using Remote Desktop.

If it turns out that this is the root cause, please safely ignore the
warning messages.

More info, please refer to:

Event ID: 3019

f this issue happens on client computers, please also refer to the following KBs:

Programs that connect to IP addresses that are in the loopback address range may not work as you expect in Windows XP Service Pack 2

You see message 3019 in the System Event log when you map a network drive or connect to a network share by using a UNC path name in Windows XP Service Pack 2

Error Message: The Redirector Failed to Determine the Connection Type


Thanks for your help. I've checked the different articles mentionned but could not come up with a solution. I've made sure I wasn't mapping twice a drive to a share, or using UNC, etc, as mentionned in the articles.

Since this does not seem to be an important error, I will simply ignore it, unless you recommend otherwise.
