Re: Unable to access server resources via vpn

Hi Terence

Many thanks. Required files sent separately.

The client pc is able to vpn successfully to several other sbs2003 server so
client pc is probably not at fault.

Running ICW and Remote Access Wizards now intermittently (mostly not) allows
remote desktop to connect using server ip 192.168.16.2. Files are also
accessible intermittently using \\192.168.16.2\MyFileShare etc. Ping is
never successful.

However I have noticed a peculiar thing on this server. When trying to
connect to local sites via 192.168.16.2 , 192.168.16.2/Remote or
192.168.16.2/Exchange, no login web page is displayed instead a windows
login box appears asking for username and password. After having entered
admin username/password three times, login fails with an error web page as
below;

The page cannot be displayed

HTTP 407 Proxy Authentication Required - The ISA Server requires
authorization to fulfill the request. Access to the Web Proxy service is
denied. (12209)

Many thanks again.

Hello John,

Thank you for posting here. Let's also thank Cliff and Eric for the input.

According to your description, I understand that you unable to access any
resource on SBS after the VPN connection is established. If I have
misunderstood the problem, please don't hesitate to let me know.

Based on my research, I suggest we try the following steps to see if we
can
resolve this issue:

I suggest we try the following steps to reconfigure the VPN on SBS and
remote clients to see if we can resolve this issue:

1) Disable RRAS

a. Schedule a network down time.

b. Please open Routing and Remote Access console on SBS thru run command
"rrasmgmt.msc"

c. Right click the SBSname (local), select Disable Routing and Remote
Access console

2) Run CEICW on SBS

You have to rerun the CEICW to make sure your SBS 2003 server have right
network configuration. Go through the follow KB and Rerun CEICW again
carefully.

How to configure Internet access in Windows Small Business Server 2003
http://support.microsoft.com/kb/825763/en-us

3) Run Remote Access wizard

a. On the Small Business Server 2003-based server, click To Do List in the
left pane of the Server Management console.

b. Under Network Tasks, click Configure Remote Access.

c. Click Next, click Enable Remote Access, click to select the VPN Access
check box, and then click Next.

d. Type the fully qualified public domain name (your public DNS name) of
your server, click Next, and then click Finish.

e. When the wizard is completed, click Close.

4) Then you can access RWW to download Connection Manager or copy the file
from SBS server c:\ClientApps\Connection Manager\SBSPackage.exe. Please
save the sbspackage.exe file in VPN client computer. Then double-click
SBSPackage.exe to run it. After this file run the "connect to small
business server" will be created and you can use it to connect VPN to your
SBS server.

If we cannot resolve the issue after we perform the above steps, please
help me collect some information for further investigation:

1. Once the VPN connection is established, run command "ipconfig /all >
c:\ipconfig_sbs.txt" and "route print > c:\route_sbs.txt" on SBS, send the
files c:\ipconfig_sbs.txt and c:\route_sbs.txt to me at
v-terliu@xxxxxxxxxxxxx

2. Once the VPN connection is established, run command "ipconfig /all >
c:\ipconfig_client.txt" and "route print > c:\route_client.txt" on
problematic VPN client, send the files c:\ipconfig_client.txt and
c:\route_client.txt to me at v-terliu@xxxxxxxxxxxxx

3. Gather MPS network report on SBS:

a. Download MPSrepot_network from
http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd9
15706/MPSRPT_NETWORK.EXE

b. Run MPSRPT_NETWORK.exe on the server box.

c. The tool will automatically collect the information. This procedure
will
take 10~15 minutes.

d. Open Windows Explorer, navigate to the folder:
%SystemRoot%\MPSReports\Network\Reports\Cab\

e. Send the .cab file directly to me at v-terliu@xxxxxxxxxxxxx

I hope these steps will give you some help.

Thanks and have a nice day!

Best regards,

Terence Liu (MSFT)

PPTP, Server=sbs2003 remote access works OK via RWW, client=winxp dialup

2) Are you running SBS 2000, 2003, 2003 R2, Standard, Premium?

sbs 2003 premium

ISA but it is configured for remote access

Thanks
