Client has 2 virtual servers, ESX 5.5 and 6 platforms. 1 AD/Exchange server, 1 SQL server.
Client has an 2011 SBS network, 25 or so workstations. I have called IP host several times (Level 3 Communication), no service issues. I have AD, DNS and Exchange installed. I have the correct DNS zones for IPV4 and IPV6, though we are not using IPV6. System has been in place for years. I have domain web page IP entered as www in DNS zone. Issues are,
1. Users cannot get to the company web page without a HOST entry on their PC. Get page cannot be displayed error without the host entry.
2. Getting many different web pages cannot be displayed, or slow accessing web pages. Could be any web site, Yahoo, MSN, web site, news, mail, etc. Users can click on a web page, get resolving page messages from Chrome, and then it may or may not open, gives you a page cannot be displayed error, and then more times than not, will open in the end! IE 11 is no better, spinning circles, etc.
I have a trusted domain certificate SSL from Go Daddy, ran fix my network wizards several times, purged out DNS computers.
We have a Gigabit Netgear router with Static IP, and DNS pointing to the ISP DNS servers. A static IP is in the network adapter, the other adapter is disabled, and the server points to itself for the DNS in the network adapter settings. I have reset all the hardware, pulling the hair out on this one, checked all I can think to check, does not happen all the time, some users more affected than others, happens on the 2 servers as well.
Any ideas? Can I "redo" the DNS system? remove and re-install? Would that cause more issues than what it's worth?
