Apply the SNA Server 2.11 Windows 3.x hotfix, or upgrade the Windows 3.x client to SNA Server 3.0, and add the following entry in the [wnap] section of the win.ini:
```
      211ResLoc=Yes
```

Microsoft has confirmed this to be a problem in SNA Server versions 2.11 Service Pack 1 (SP1) and 3.0. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
