Hello Customer,.
Thank you for posting here.
According to your description, I understand that the VPN clients can
dial-up and authenticate and get the internal IP address, but they can't
access share folder. If I have misunderstood the problem, please don't
hesitate to let me know.
Based on my research, this problem occurs mostly because of a change in
Windows Server 2003 SP1. Windows Server 2003 SP1 enables the
BootTimeSecurity registry entry. Therefore, after you install Windows
Server 2003 SP1, the Windows Server 2003 Ipnat.sys driver drops VPN packets
that it receives.
You can find more information about it in:
VPN clients can no longer access internal resources after you install
Windows Server 2003 Service Pack 1 on a computer that is running ISA Server
2000
http://support.microsoft.com/kb/897651/en-us
I suggest that we try the following steps to see if the problem can be
resolved:
Step 1: Contact the PSS to obtain the hotfix 897651 (the link above) and
apply the hotfix on the SBS Server.
(You must restart the computer after you apply this hotfix.)
Step 2: After you install this hotfix, you must set the value for the
following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IpNat\Parameters
You must set this value as follows:
Value name: DisableBootTimeSecurity
Value type: REG_DWORD
Value data: 1
After these 2 steps, if VPN clients can't access Internet, I suggest we try
to manually create a VPN connection on the remote client through the
following KB article:
How to configure a VPN connection to your corporate network in Windows XP
Professional
http://support.microsoft.com/?id=305550
Then we can try following steps:
Not using the remote gateway on the client, to do so:
On the remote client
1). Double-click My Computer, and then click the Network and Dial-up
Connections link.
2). Right-click the VPN connection that you want to change, and then click
Properties.
3). Click the Networking tab, click Internet Protocol (TCP/IP) in the
'Components checked are used by this connection' list, and then click
Properties.
4). Click Advanced, and then click to clear the Use default gateway on
remote network check box.
If the issue persists, please kindly help me collect some information for
further investigation:
1. Does the problem occur on all remote VPN clients?
2. Try to access share folder via \\ServerIP\ShareName, is it work?
3. Try to access share folder via \\ServerName\ShareName, is it work?
4. Please gather the outcome of command ipconfig /all on VPN client and SBS
server after you setup VPN connection.
Hope this helps.
Thanks and have a nice day!
Best regards,
