WNAP /User: Parameter and /Pwd: Parameter Do not Succeed In SNA Server 3.0 (171255)

SYMPTOMS

An SNA Server client running the SNA Server 3.0 (or 3.0 SP1) Windows 3.x client cannot establish a sponsor connection to an SNA Server if Wnap.exe is autostarted using the /User: and /Pwd: parameters to automate the client logon.

The following is an example of a WNAP command that uses these parameters:

wnap /user:<username> /pwd:<password>

where username is a valid Windows NT user name and password is the password for this user name.

When the sponsor connection fails, you receive the following error message:

SNA Server Warning: 629
No SNA Server Configuration Broadcast received.
A Server must be available before you can use 3270 or APPC.

The problem does not occur if the parameters are all uppercase.

The /User: and /Pwd: parameters are documented in Appendix A of the SNA Server version 3.0 "Planning Guide."

CAUSE

The Wnap.exe program that is included with the SNA Server 3.0 Windows 3.x client does not correctly parse the /User: and /Pwd: parameters if they are entered in mixed case or lowercase.

RESOLUTION

To work around this problem, when you autostart WNAP, specify the two parameters in uppercase as shown here:

wnap /USER:username /PWD:password

NOTE: The arguments that you enter for USER and PWD do not need to be uppercase.

The Wnap.exe program has been updated to correctly parse these parameters in all cases.
