I have, as a result of a system replacement, a brand new Vista Ultimate machine courtesy of Dell. I de-installed the Trend Micro Internet Security and use only the Windows Firewall as I am behind my router SPI firewall. My router is a Linksys WRT350N. My anti-virus is Grisoft AVG (antivirus only).
I've discovered that Vista will not connect to microsoft servers, specifically, Windows Update gives error code 80072EFE (though automatic background updates seem to be working), Windows Mail gives an error of 0x80042820 when trying to connect with Hotmail (will poll my POP3 accounts fine), Windows Live Messenger gives a error of 80048820 and an extended error code of 80048416 when trying to log in, and Windows Media Player will not connect to the upgrade server.
Also while I can navigate and see the microsoft.com and hotmail.com sites, I cannot sign in to my hotmail account through the hotmail.com site with I.E. 7. I can sign in if I use Firefox. It is as if all my Microsoft software will not talk to Microsoft. No other problems with the internet other than that. No problems with I.E. 7 other than that.
I have tried with the firewall turned off and still the same result. Oddly, enough Outlook 2007 will sync with hotmail, but Windows Live Mail will not. Never had this problem with XP pro.
I am stumped. Can anyone help? I'd like to be able to use Messenger and Windows Update if nothing else.
