The Perle 833 is only responsible for establishing a PPP connection so that the Windows client can communicate through it to devices on the network (such as Domain logon messages).

Login scripts, password expirery messages or drive mappings are not processed as no Domain login actually occured.

The workstation initiates a Dialup Networking connection to the Perle. A PPP connection will be negotiated.

Once the PPP connection has been established the Windows client will then try to initiate a Domain logon. The Client will communicate to the Domain controllers via the Dialup connection.

Windows comes in 9x based and NT based versions. Both have a different method of configuration to log onto a remote network.

Windows 9x:
Network Properties - Client for Microsoft Networks:
Enable "Log on to Windows NT Domain"
Configure the remote Domain name.
Dialup Networking - connection properties - Server Types:
Enable "Log on to Network"

The Windows 9x client will use the UserID/Password that was used at the initial Windows Logon prompt to log into the remote Domain.

Windows NT base:
When a Windows NT based system presents a Logon prompt there will be a checkbox that states "Logon using dial-up Connection". This must be enabled so that the client does not logon locally.
Enter the UserID/Password/Domain of the remote site and Windows will present a list of Dialup Networking connections to use.

Note: Windows clients will utilize broadcasts to locate Domain Controllers. These broadcasts will not be passed through the Perle 833's, so one or more of the following will have to be implemented depending on your Domain type:
LMHOSTS file
HOSTS file
WINS
DNS
