Re: Clients not able to ftp

I already have a EnableRSS record in my registry. It has a value of 1. Should
I replace the 1 value with 0?

Hello Thomas,

Thank you for posting here. And thanks for Cris's inputs.

According to your description, I understand that you can access external
FTP site from command line but cannot access it from IE after you install
windows 2003 sp2. If I have misunderstood the problem, please don't
hesitate to let me know.

Based on my research, this problem is caused when the software hash code
for the connection and the hardware hash code for the connection do not
match. Receive Side Scaling works by offloading the TCP secure hash
function to the network adapter hardware. Therefore, the network adapter
calculates the hash value for the connection when Receive Side Scaling is
enabled. Internet Connection Sharing also modifies the addresses and the
ports that are provided by the IP header for the connection. When this
occurs, the hash value that is generated by the network adapter is
invalidated. When the invalidated hash value is used, the TCP connection is
reset.

This problem may also occur if the IP source address, the IP destination
address, the TCP source port, or the TCP destination port are modified
during receive processing. These addresses and ports are provided in the
TCP and IP headers for the connection. This problem may occur in some NAT
scenarios.

I suggest we try the following steps to see if we can resolve this issue:

Warning: Serious problems might occur if you modify the registry
incorrectly by using Registry Editor or by using another method. These
problems might require that you reinstall the operating system. Microsoft
cannot guarantee that these problems can be solved. Modify the registry at
your own risk.

To work around this problem, disable Receive Side Scaling when the computer
is configured as an Internet Connection Sharing gateway. To do this, follow
these steps:

1. Click Start, click Run, type regedit, and then click OK.

2. Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

3. On the Edit menu, point to New, click DWORD Value, and then type
EnableRSS.

4. Double-click EnableRSS, type 0, and then click OK.

Hope these steps will give you some help.

Thanks and have a nice day!

Best regards,

| Clients can only ftp by using command line. Clients could ftp last week.
| Installed Windows 2003 SP2 over the weekend. Now no FTP. ouch.
