     for an affected fileset, then determine if
     a fixed revision or the applicable patch is
     installed.

 B. Recommended solution

**REVISED 01**
     CAUTION: If you have installed a web upgrade, the Base OS
              version remains on the system.  This command:
                 "/usr/bin/enable_inet -r bind"
              restores the Base OS version.  The Base OS version
              cannot be patched while the web upgrade version is
              enabled.  After reverting to the Base OS version
              you should verify that it is properly patched as
              described below.

     The following fixes are available:

      HP-UX B.10.10
      HP-UX B.10.20
