I'd appreciate some assistance

I have 2 ISA servers configured as an array in their own Win2k forest. They are 
in integrated mode and protect an Internal Win2k network.
The internal interfaces have network load balancing configured. The internal 
clients are terminal server clients and their proxy settings point to the 
virtual IP address.

The external interfaces are independent (NLB can only be done on one set of 
interfaces I discovered).

The external interfaces both accept VPN connections (Load balanced by the ISP 
round robin DNS). From a Win2k Prof client I can quite happily create a PPTP 
tunnel to either ISA Server and then ping internal machines, or connect to 
netbios shares. I can also run a terminal services client on my machine and 
connect to internal servers.

The problem: (at last)

When I connect to the VPN from a Win98 client with the Microsoft VPN Adapter 
installed. I can still happily ping internal machines, but everything else is 
intermittent at best. I have successfully connected to C$ shares on the dc's in 
the internal forest. 

I have 40 remote users who will be using this VPN who all have Win98 or Win95 
installed.

A more minor problem is that the Virtual IP address also works periodically 
although this is for like 2 days and then stops working.

I recently read a post from Thomas Schinder that referred to a post by Jim 
Harrison explaining some of the problems with pre Win2k clients. I am unable to 
find this post though. Would you mind reposting this please Jim?

If anyone can shed any light on my problem, make suggestions or needs further 
info then please let me know.

My head aches.
