itunes cannot verify the ID of server error message

[alsal]

I have been having a big problem with iTunes.
I have itunes installed on a Windows 8 machine which was migrated over from an old XP machine. Everything works for my account. I have now tried to set up my wife's account. I created a new Win 8 account (local) for her and set up iTunes. All of her music populated in the library. I then tried to establish connection to the iTunes store and got the following error:

"iTunes cannot verify the identity of the server init.itunes.apple.com. The certificate for this server was signed by unknown certifying authority" It then goes on to say that it may be an impostor server and proceeding could be dangerous or words to that effect. It gives a choice of "continue" or "cancel."

I have been hitting continue and it leads to more popups with similar server errors for "p.36.buy.itunes.apple" and "xp.apple.com" and "upp.itunes.apple.com"

Finally after all of that the store window opens but it is blank.

I have searched this forum and apple's and have not found a solution. I tried clearing the cache and I even re-installed itunes. Pretty frustrating!

Any help for this? Thanks!

Did you remember to shut down iTunes on your account before opening it on hers?

iTunes does not play well with user switching.

Is her account not an administrator account? It should be.

Is her clock set to the correct time? If it is off, then certificate validation will fail.

There is a connectivity test web page: iTunes for Windows: iTunes Store connection troubleshooting
And an Advanced page: iTunes: Advanced iTunes Store troubleshooting

Thanks for the response!

To answer your questions, yes, I shut down iTunes on my account and even logged out of my Win 8 account before logging on to hers.

Yes, when I created the local account I made her an Administrator.

I checked the clock and it is accurate.

After checking all of those, I followed some of the links you suggested. Unfortunately, many of the proposed solutions have not been updated to address Windows 8. I did, however, follow a suggestion that I go into Internet Options and LAN settings and under Proxy Server, DESELECT "Use Proxy Server for your LAN". Once I did that, voila, the error popups stopped and I was able to connect to iTunes store! However, just to test it, I closed out iTunes and started it again and popups re-appeared and no store connection. I went back to Internet Settings and lo and behold, the Proxy Server box was checked again! I deselected it and once again no problems. Clearly this looks like either a Win 8 issue or I may have some malware causing this but it appears that the solution to this issue is the Proxy Server selection.

Query though; why did this only impact my wife's account? I never had those problems with my account despite the Proxy Server box being checked? Curious if anyone knows the answer to this.

There is a Windows 8 issue: LAN Connection settings keep changing back to proxy server after - Microsoft Community

Apparently there is a fix in that thread.
