Win2000 Pre-SP4 Hotfix "Q320206"
Standalone PC, Dial-up
Netscape 7 PR1 and MSIE 6.0

I can't seem to upload much at all.

I can download everything, AV updates, work units for S@H, G@H, F@H etc.
I can send from my Netscape.net mail account inNS 7PR1, IMAP/SMTP server.
I can send to some message boards, but I needed to use my OS X machine to send this.

I cannot upload anything to SETI-, Genome-, Folding@home or distributed folding. I know that S@H has some problems, but all of them?

I cannot send email from my normal POP account. POP and SMTP servers have the same name: mail.bigpond.com I receive email OK. (But I can send email from the POP account if I dial into it from my mobile phone.) I usually get an SMTP failed orrefused error after browser upgrade, but deleting the SMTP reference and then adding again does the trick. Not this time.

Cannot send email from POP account using Outlook Express. Receive OK.

I may have stuffed things up when applying the last Win2k hotfix, but uninstalling it doesn't help. I un-, re-installed the TCP/IP protocol. I tried some suggested Registry settings. No good

Where should I try next? (I might just reinstall Win2k.)

Has anything changed? It sounds like to me that you are now behind a firewall/proxy server. All you traffic has to be sent to a proxy server for internet access. I would check with either your ISP or Network Administrator.

HOpe this helps.

My previous Zone Alarm installation may have changed some settings which have had a flow-on...
No proxy server.

I was using Zone Alarm, but I uninstalled it after the problem appeared. The Hotfix is the most recent change.
My ISP doesn't use a proxy server.

Sounds like your not logging on correctly (password).? or you have not created a user account, either at the machine or at your pop3 server. Try redoing the account both on the local machine and at the pop3 server.

Win2000 TCP/IP is mostly self-tuning.
The @home clients are uploading 1500 byte packets at 10-15 second intervals but aren't getting a reply.
I think that all registry values are at default, but maybe something there is clobbered.
Eg. Tcp1323Optsvalue doesn't improve the situation.

It sounds like oyu have DSL or Cable?

Go to DSLreports.com

download a utility called DRTCP. Read the instructions on the web site.

I had a simular problem and this fixed it.

by braddles

I don't have DSL or cable, but DrTCP does work with dial-up with Windows 2000 or XP.
MTU value set to 576 and it worked.

by braddles

Email POP is working after I deleted and adding the SMTP server value about 20 times. :(

Still cannot upload from any command line @home client.

by braddles

I thought that Windows 2000 had self-tuning networking, so I was reluctant to change the very value I used to tweak on my old Windows 95 PC.

I tried to PING using some packet sizes and found that 1500 didn't work and 576 did!
Changed MTU to 576... problem solved.
There is probably more tweaks to be done, but at least I'm talking.
