Question about Microsoft Windows XP Professional
I am baffled. I have used LinkedIn without issue with Windows Vista for well over a year. All of a sudden it started tanking on log in (says there is no connection to the internet). I downloaded Chrome and it workd for 3 days and then did the same thing. Firefox didn't work. I then tried this on another home laptop with Vista and had the same challenge (didn't work on IE, worked for about 3 days with Chrome then stopped working, never worked with Firefox). I've been talking with LinkedIn for 3 weeks and they have no solution and claim no one else is having the problem. I find this shocking as I can't log in with my account to ANY Vista machine successfully. I can log in to any non-Vista machine with the same account and it works just fine.
Please tell me you have seen this problem and know exactly how to fix it.
I found a solution for *my* problem, by shrinking the MTU in my router.
I have two Vista PCs at home that can't access LinkedIn's sign-in page.
I was suspicious that several browsers seemed to be having a problem, which made me think it was either a virus middleman in the network code, or a router problem. I eliminated the virus possibility by replicating the problem on another PC.
By changing the MTU on my home router from Auto to 1452, I got the signup page to appear.
It appears that Windows Vista's new TCP stack does some advanced segment and window sizing and that didn't work with my Linksys RV042 router's Auto MTU setting. I'm not 100% sure what it is about LinkedIn that caused a packet of just the wrong size, but this is the second time I had to tweak this router to work with Vista. First I needed a firmware upgrade to get some traffic flows to work at all, and now this MTU change.
I do know I've had to change MTU settings in the past to work with encapsulation protocols like PPPoE, but I haven't had to change the MTU setting for quite some time...
Maybe this clue will help someone else...

And Start > Run > type in "ipconfig /flushdns"; hit return (leave out the quotes)

It sounds like you have connection issues.
For starter please consider disabling your firewall (under control panel) then try connecting.
If this doesn't work please try reseting internet explorer settings (under explorer-tools).
Check with tech support of linkedln to see if they require special internet explorer security settings and have them walk you through your settings to make sure nothing has changed.
Last but not least I'd try to go to system restore and restore to a point where you are sure evrything had worked like couple of weeks ago or even one month ago if possible.
(start-programs-accessories-system tools-system restore).
The system restore tool doesn't erase or change any data although if installed any program since that point you are going to have to reinstall it since system restore will restore all registry information to that specific point and disregard everything you did afterwards, therefor I'm going to have to tell you to use at your own risk.
Thank you for using agadycom.
