[pptp-server] Connectivity Problem

[System Administrator]

I still have yet to get any information back from the list in regards to
my problem.  Here are some more interesting facts that I hope will help
shed light on the problem enough that someone can give me a hand.

The problem I describe below occurs when I connect a win98 or win2000 box
to the vpn.  I installed the linux pptp client software and was able to
successfully connect and work for hours with no problems like the ones
below.  I tried the windows connection again and once again experienced
the loss of connectivity.  This time I noticed a few interesting log
entries:

Jun  6 20:37:05 ringworm kernel: Not enough space to encrypt packet:
1504<1504+4!
Jun  6 20:37:06 ringworm kernel: Not enough space to encrypt packet:
1504<1504+4!

Perhaps this may be the cause of the problem?  I don't see these messages
when I connect with the linux client.  Any help or ideas would be greatly
appreciated.

Thanks,
