Changed DNS, now portal is broken.

Question

Hey folks,

We recently switched internet up in the office which entailed the web mapping server getting a new DNS. This has broken Portal 
 Now, this is the page I get.

web.vectorgeomatics.com load my test page fine, web.vectorgeomatics.com/portal/home gives me said error.

If I remote desktop into the server that portal/server is hosted on and I go start > arcgis web adaptor (portal or server) it tries to load the localhost https://localhost/portal/webadaptor and I get the "There is a problem with this website’s security certificate." and If I hit continue it just loads "The webpage cannot be found".

Anyone have any quick ideas that might fix this short of having to reinstall /  re set everything up? Thanks

DNS server, domain name retained. Had no idea what happened, ended up reinstalling Portal and its normal again. Thanks for the help folks.

Did the domain name of the portal change, or simply the DNS server but the original domain name was retained?

try the ..:7443/arcgis/adminpanel and look at the log files. if this is not working, then look in the portal's log files located here: \logs\\portal There should be some errors that make it a little more clear what's going on. you may need to talk to your network person at some point. if you just want to look, in windows, using a command prompt or powershell, and check the network configuration.. "ipconfig /all" will tell you what the machine name is and what ip is and confirm with the network person if it's right. ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : TEST-Machine-N1 Primary Dns Suffix . . . . . . . : test.machine.com Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : test.machine.com pwc.uis Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Intel(R) PRO/1000 MT Network Connection Physical Address. . . . . . . . . : 00-50-65-FA-74-FC DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 60.80.170.144(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 60.80.170.129 DNS Servers . . . . . . . . . . . : 190.160.240.20 NetBIOS over Tcpip. . . . . . . . : Enabled
