Hello,
I have two locations that i want to connect to each other with VPN.
Both of the two locations have a domain controller and tmg server serving as internet proxy, but there is two completely separate active directory domains.
Location 1 :
AD1.site1.loc as domain controller of domain SITE1
TMG1.site1.loc as proxy server of domain SITE1 with public ip address IP1
Location 2 :
AD2.site2.loc as domain controller of domain SITE2
TMG2.site2.loc as proxy server of domain SITE2 with public ip address IP2
I configured PPTP site to site VPN connection in both of TMG1 and TMG2, but when trying to initiate connection i have an error in the event viewer :
User TMG2\Site1 is connected from IP address IP2 but failed trying to authenticate due to the following reason : the specified username and password are not recognized or the selected authentication protocol is not supported in the remote site
I precize, that TMG2\Site1 is a local account with permission of remote access, and has the name of the remote site configured in TMG2. Same thing, is configured in SITE1. And same error is found in the other TMG server.
What can i do to resolve this issue, please?
Thanks in advance, and regards.
