RE: Download file issue - FTP & Web

Hi Ted:
Based on my further research, this problem could also be caused by the
EDNS0 query.

Windows Server 2003 supports Extension Mechanisms for DNS (EDNS0) function
which permits the use of larger User Datagram Protocol (UDP) packet sizes.
However, some firewall programs or routers may not permit UDP packets that
are larger than 512 bytes. As a result, these DNS packets may be blocked.

I would like to suggest you try the following steps:

1. Insert SBS 2003 CD2, navigate to \Support\Tools\ Double-click
suptools.msi to install the Windows 2003 support tools.

2. At a command prompt, type the following command, and then press ENTER:

"dnscmd /config /enableednsprobes 0" (without the quotation marks)

The following information appears:

Registry property enableednsprobes successfully reset.
Command completed successfully.

After you run this command, Windows Server 2003 DNS no longer advertises
its EDNS0 capabilities.
As a result, the Windows Server 2003 DNS server will not be sent UDP
packets that are larger than 512 bytes.

For more information, please refer to this KB article:

828263 DNS query responses do not travel through a firewall in Windows
Server 2003
http://support.microsoft.com/?id=828263

In addition, since you have installed the SBS 2003 SP1, we also need to
appy the following fix to see if the porblem can be solved, please read
this KB article and install the corresponding patch onto the SBS server:

898060 Installing security update MS05-019 or Windows Server 2003 Service
Pack
http://support.microsoft.com/?id=898060

Hope the above info helps. Please feel free to let me know if there is
anything I can do for you.

Have a nice day!
