Stefan - I have just checked the archives and I don't see my reply to your
message. Maybe you didn't get it either so I'm sending it again.

Hi, thanks for the reply. I have put two Ethereal traces, fast and slow on
ftp.chf-ga.org - anonymous access allowed.

The only consistent differences I have been able to detect are:
Slow, Packets 31-32 then 39-40 show the enumprinters followed by the Invalid
Name response. This sequence is repeated for all 90 hosts across our wan
that have a shared printer.

Fast, Packets 69-70 Enumprinters followed by Insufficient Buffer response,
with what I guess is the minimum buffer size required.Packets 106-132 are
the repeated Enumprinters with responses, eventually listing details of the
actual printers.

In both cases, there was at least preceding NetServerEnum2 call to a BDC
that got a response list hosts that had shared printers. Fast 41-42, Slow
14-15.

The printers.pdf file shows the results of a working 'fast' scan. In the
Slow case, it is only the hosts that are displayed in the browse list,
without the two  rows of printer details at the top of the list.

As I said in the first post, the problem seems to have gone away after ten
days, but I would like to find out if it is symptomatic of another, maybe
routing, problem. The reason I suspect some sort of networking issue is that
it was first noticed after a central layer 3 switch was restarted, but I
just can't see how it is related.

Thanks
Neil
