Do you dial right into there system or are you lucky enuff to have a global dialer? Say bell or sprint or something. I once had a custemer that freaked out because he dialed right into the system and it worked 1% of the time, turns out there were 5 reps fighting for the connection every night. I almost died
Oh! Also if your using Cisco/Nortel vpn clients try checking on the group password. Im still a little new to trouble shooting this stuff but I hope Ive helped in anyway
