Title: VPN works with XP, not 98SE
Post by: Vince Levalois on March 28, 2003, 01:08:59 AM

I'm able to VPN (to a 5.6 Update 2) with no issues on an XP client, however it's a different story with 98SE.

I've made sure to have the 128 Bit Encryption DUN on 98 and set the properties of the connection to encrypt the password and data.  Regardless of the settings, I get "error 645".

Additionally, here's the messages log:

I can see that there's that MPPE peer negotiation failure, but I don't know how to solve that.

Any helpers?  

Thanks.

Had the same problem before. Installed the latest DUN update to fix it. I think you can find it here http://support.bumc.bu.edu/vpn_ppp/download.htm

Good Luck!
