I have computers that should be able to login to network with both lan and
wlan connections. With lan connection everything works fine. However, when
login with wlan no mappings are done in login script. Get error 8801 on
every drive, but login is successful. Manual map works fine after the
computer logs on.

Could SLP be the problem? When will the PC get in contact with the DA?
Should I use IP addresses instead of servernames in login script? Or is thee
any other parameter I could use on the client to fix this problem?

The reason why I dont want to use IP addresses is because we are running
cluster services, and would be able to use failover.
