Hi ;
Someone who has VAX6220 may interest in this network problem !!!!
*************************************************************
*************************************************************
Currently our campus network was designed to allow student use
PC running DECnet/DOS v 1.2 through DEMPER direct connect to Ethernet
backbone. One of our VAXcluster 6220 (VMS 5.0-2 two processor)
suddently became network resource unavailable. I checked users at that
moment only 11 users on the system but when I checked NCP> show know
link, there were lots of unknown processors occupied the line.
I call DEC Colorado for help.
The unsatisfied answers are:
***************************
" When you log in and log out of VAX6220 using DECnet-DOS v 1.2 through
DEMPR and did not turn off P.C. right away. VAX will still reconize
you still hanging there wear an unknown mask. That's why the unknown
processors from."
I am doing some test now including update the DECnet-DOS version and
modify NCP parameters. But if someone has the same experience I had
please let me know.

We have a similar network problem. Our network consists of a Vax-cluster with a 8350 (2 cpus) and a 8600. We have over 200 DEC PRO 350s as end nodes distributed across the campus. Students access the VAX 8350 using Remote terminal software ( similar to SET HOST) on PROs. Even though, students logout we see multiple links with a zero pid (00000000) when we give NCP> SHOW KNOWN LINKS command on the VAX. We explained the problem to DEC Colorado support center. So far they have not come up with any explanation or solution. To make the links disapper we shut down the Decnet on the VAX and bring it up again from time to time.
