VPN and LAN conflicts

Guest

I have configured my SBS 2003 server to allow the routing and remote access
service to be a Route Access server only (i.e. not to act as a router) and we
are able to VPN in and everything works great. But when we go to log into our
network via a LAN connection (when we startup our computers at work), the log
on process is VERY slow (the boot up process on the XP clients "applying
personal settings" for example takes an extraordinarily long time) and the
connection is spotty (i.e. Outlook’s exchange connection is dropped
frequently.) Then if I disable the routing and remote access service, our LAN
connections work great but we cannot VPN in. FYI, all of our SBS 2003
infrastructure is on the same computer. We have a router that connects us to
the Internet but the SBS 2003 server performs DHCP, DNS and NAT. Any ideas
how I can configure the RRAS to make the LAN connections to work more
efficiently while enabling the VPN?

Sounds like name resolution issue. Open the DNS Manager and check the A record. Is it possible the server registered two different IP addresses, one for the LAN IP and another for the VPN?

Let me ask you this. When I expand my forward lookup zones, there are 2 sub
folders: (1) mydomainname.local and a second for _msdcs.mydomainname.local.
Then when I go to the reverse lookup zones and expand my subnet, there are 2
A records the same local IP address that assocate the same IP address with
_msdcs.mydomainname.local. and mydomainname.local. Could that be an issue?
Why do I have 2 instead of just one sub folder in the forward lookup zones?

Have not head back re my post - and the problem still occurs. I tried to fix
by implementing the steps in the article
http://www.howtonetworking.com/casestudy/rraswithdcdnswins1.htm (even though
we are not experiencing the symptoms it is a computer that runs both RRAS and
DC, DNS and WINS).

It just seems very odd that the VPN works great but logging onto the network
when plugged in the LAN each stage of the process (Preparing network
connections, applying computer settings and applying your personal settings)
takes forever! If I stop the RRAS service then the logon time is normal.

I’ve tried searching the web for other solutions but have had no luck –
please try again to help. Thanks.

Any errors in the event viewer after establishing the VPN? Do the DNS have two A records with different IP addresses pointing to the same server? Or posting the result of ipconfig /all here may help.

There were no event errors in the log.

Let me also mention this if it will be helpful: When I boot up conected to
the LAN I cannot get passed applying your personal settings. Then I unplug
the LAN cable, boot up and plug the cable back in. I can now ping all
machines and access the web but I cannot connect the the Exchange server.
Even my mobile phone cannot activesync with the exchnage server. After I stop
the RRAS service evything returns to normal. FInally, I only have RRAS
configured to act as a romte access server (i.e. no routing).

Thank you very much for your help.

After connecting to the RRAS, the server should have PPTP IP information. I don't see it.

Hi Craig!

I have the same problem on my SBS server. When I connect the laptop in the
network everything is slow, especially the outlook 2003, The only diffrence
is that I have 2 NICs in the server and I am not running ISA.

Would be really glad if you find something that you can share with me?

Since you have two NICs enabled, make sure they are setup correctly. Or posting the result of ipconfig /all here may help.

I\ve looked and the errors in dns is old. But everytime i connect the laptop
the exchange is hopeless slow on the other computers. Know I have uninstalled
both the AV and Outlook 2003 on the client, but exchange is still slow for
the other user, about 30 min for one send/recieve. If I disconnect the
network cable from the laptop or turn it down, it runs fast again.

I've spend 8 hours yasterday troubleshooting this error. What I found out was
that one computer running VPN and 3g mobile accesscard was causing the error
with the exchange server going slow. I reinstalled the computer from scratch,
connect it to the server with the same computername and the network was slow
againg. I took it out from the network and created another computer on the
network and connected the computer again. Now everything was fast. I've
installed all software and it was good till I installed the 3G card and
restared the system after this. The 3G Card installs odysses client under the
network protocol list. Now it was slow. I took the computer out of the domain
again to a workgroup and again it is fast. This is how I run it now till I
have a solution. Now they just called and said it is slow again.
