Locked my previous users out...ouch!

[desert_dave]

I'm not sure what or why it happened, but here's what I did.
1. Moved cpg 132 from /coppermine/cpg132 to /gallery via a copy and upload.
2. Re-installed my Mysql Db from a backup for phpBB2 & cpg132.
The result; everything is fine except....
Now I have 3 previous registered users that cannot access the site. They get nada, not even able to ping the site, but fine for any other url they try. I almost seems like I've blocked their IP but I'm clear in config and deleted one account to see if that would help, which it didn't.

Anyone have even a wild guess on this one?

I contacted my web server and had them check one of the users IP and they said it was a problem somewhere in my users network connection. I'd buy that except that all 3 users are spread around the country and on different ISP's. And with all of them having the same problem on the same day after my changes, I can't buy into that explanation.

If there's not even a ping from the domain (you can't ping subfolders), while there is a ping for others, the issue you're facing is certainly not related to moving coppermine files around on your server (although not being able to ping a domain doesn't necessarily mean you can't access it in your browser by http). To tell you more, you will have to post your actual domain and the ISPs the users are with. Make them do a tracert to the domain in question - and check what actually fails: does the name of the domain get resolved to an IP address. What hop of the tracert times out? I'd rather suggest your users have applied silly settings on their client pc (could be some personal firewall setting for example), or cached name resolutions.

No silly settings, everything was fine with them till I did my changes. We did 2 tracert's and one has this info:

Host lookup failed
Error 11004
Code WSANO_Data
Description: Valid Name, No Data Record of requested type

The other user is in Maine and my server is in CO. He times out in AZ after 8-10 hops.
He can access 2 different servers at the web hosting co there but none of my 6 sites there.

You gave yourself the answer: if DNS lookup fails, ask your webhost for support. If they don't know an answer, ask your visitor's ISP for help. A workaround would be to manually add other DNS servers to the network settings on the client PC that actually has issues with this, to enable the client pc to look up domain names from other servers if the initial name server fails to look it up.
