dial up error 633 in vista

[Guest Del Brocco Andrea]

I have the following problem:

when i try to use a dialup connectcion with a modem (i've tried with 2

different modem) in my notebook i have the ras error 633.

 

If i open the modem with a terminal i can interrogate succesfully,

also in the rpoperties of the modem the diagnostic is ok.

 

I have tried to enable the ras log and it seems unable to open the com

port.

 

i have scanned with all anti-virus/dialers, etc but no results.

 

how can i re-install ras client ??

 

the modem drivers is vista compatable (one is internal one is on a

express card).

 

i have tried to unnstall antivirus/firewall (kaspersky7), to logon as

a new user, enabling disabling services, etc.etc.

 

please help me
