vpn 0xc0040021 error - 2.Jul.2004 8:52:00 AM

I'm running the release version of ISA 2004 and eveything is working great except I have one VPN user that is having connection problems. He does connect from his home computer but states that it takes anywhere from 10 to 30 minutes to start having access to internal network resources. No one else is having this issue. ISA is showing the following alert when this user connnects:

The VPN connection attempt by user from VPN client IP address 69.140.X.X could not be established. The failure is due to error: 0xc0040021

Anyone else seen this?

Thanks,

Vince

Hi Vince,

No problem!

Is that user using a DSL line?

What VPN protocol are you using?

Is the user connecting from a network on a different network ID than the network ID your VPN clients connect to?

Thanks!
Tom

Hello
I have the same problem.
Users access to VPN but ISA Server 2004 RC1 logs VPN connection attempt by user ***@**.com from VPN client IP address 213.117.*.* could not be established. The failure is due to error: 0xc0040021.
Thank you.

Arnaud

hello,

Related to this error, I've found it many times, but the thing was related to the Routing and Remote Access Policies (Remote Access Policies). Somehow, I have to put the first policy with the right Authentication Methods (in my case, the EAP was not select when I have this error). Then, the error disappears.

Maybe this can help...

Regrads,

Mario

Just a follow-up, I got this error because the VPN Access setting for the branch user was set to "Control access via policy" instead of "Allow Access"
