Latest version of ServU is running on XP.
Clients can log in with the web client, but when they try to upload any file, it hangs after just a few KB are uploaded.
This just started happening a few days ago.
Any ideas?
As a first step, check the Serv-U logs to see if it's something that Serv-U might be doing wrong.
NOTE: A few days ago, Microsoft released their 2nd Tuesday of the month patches, which your OS may download and install automatically. There's also news that Windows XP is EOL, so that may be the last time you receive any updates from them for your OS (if they did indeed come down). If nothing stands out in the Serv-U logs, you may want to see if an update affected it. If you ruled that out, check to see if any hardware was updated or inserted between your client and server. Sometimes, firewalls/routers are updated or changed which all of a sudden causes grief for many system admins too.
Yes, thanks, that was it -- latest Microsoft update for XP.
For anyone else reading, it's KB2922229 -- uninstall that, and everything should be back to normal.
I'm glad to hear that's all it was
