Title: Start Problems Through a Filtering Bridge

Using the 3S CREATE or 3S XCREATE commands through a bridge filtering
on START service packets (IDP socket %0401) will return errors:

   **** ERROR OPENING VOLUME
   **** UNABLE TO REGISTER VOLUME XXXX
   DO YOU WANT TO SAVE THIS VOLUME ?

Here is a sample configuration:

                               FILTERS
                              /       \
              NAME,LOCATOR,START     NAME,LOCATOR,START

 NET1 netnum:123     --------           --------  NET2 netnum:123
 ____________________|      |           |      |_________________
      _|_            |BRIDGE|----T1-----|BRIDGE|       _|_
 name|   |locator    |      |           |      |  name|   |locator
share|___|start      --------           -------- share|___|start
     SERV1                                            SERV2

The SERV1 and SERV2 servers have the START services for their
respective networks.  SERV1 is defined in the NET2 name service and
SERV2 is defined in the NET1 name service.  The NET2 network administrater
links to \\SERV1\STARTDIR and runs 3S CREATE to try to create a new start
volume on SERV1 for NET1.  The 3S program can be run successfully through
the bridges because a valid 3F link has been established to the
\\SERV1\STARTDIR sharename.  3S CREATE first creates a new *.STR file on the
STARTDIR sharename, but then the procedure fails because the 3S CREATE
command cannot register the new start volume for NET1 with the NET1 start
service.  The start service packet (IDP socket %0401) cannot get back through
the bridge.

To solve the problem, follow these steps:

1.  Access the NET2 START service on the NET2 side of the bridge.  Do not
go through the bridge.  A DOS DIR on the linked STARTDIR area will show that
a startvol.str file has been created (startvol = whatever you named the new
start volume), but 3S DIR will not show it as a registered start volume.

2.  Use the DOS DELETE command to delete the startvol.str file.

3.  Follow steps 1 and 2 again from the NET2 side of the bridge.
