Portal Machine Name

Question

I have a Win 2008 R2 server aaa.yyy.com, then I installed Portal on the server. The Portal site can be created but when I access portaladmin -> machines, I found the machine name is aaa instead of aaa.yyy.com, so that I cannot import domain certificate to Portal. Are there any configurations I need to cater?

Can I rename the machine where Portal for ArcGIS is installed?

No, this is not currently supported. If you rename the machine, your portal will be unavailable.

Thanks for your reply. I have found the following entry in C:\Windows\System32\drivers\etc\hosts:

10.90.65.67 bbb aaa aaa.yyy.com

It is likely the entry lead to the problem. Are there any ways to modify Portal hostname after installation?

Hello Mats,

First, I would like to confirm if the Portal site is accessible through the fully qualified name when accessing different endpoints:

*  https://aaa.yyy.com:7443/arcgis/home
*  https://aaa.yyy.com:7443/arcgis/portaladmin
*  https://aaa.yyy.com:7443/arcgis/sharing/info* Note: Portal 10.5.1+ will need to be  https://aaa.yyy.com:7443/arcgis/sharing/rest/info

If the Portal site is not reachable over the fully qualified name aaa.yyy.com, recheck that the machine is properly joined to the domain.

Next, review the [C:\Windows\System32\drivers\etc\hosts] for any entries, especially entries that are not fully qualified or incorrect. Portal prefers to use localhost to identify itself, so if entries specify localhost to the shortname aaa, this may be the issue.

If DNS (Domain Name System) records are incorrect, this may also confuse Portal. Use the Command Line tool nslookup to confirm the machine can resolve localhost, aaa.yyy.com, and the IP address for aaa.yyy.com (called a reverse lookup).

Example from cmd.exe:

> nslookup aaa.yyy.com

Server: dns.yyy.com  // DNS server being queried

Address: 10.11.12.13 // IP address of DNS server being queried

Name: aaa.yyy.com

Address:  10.20.30.40 // IP address on record for aaa.yyy.com

I am interested if ArcGIS Server is also installed on the same system, does it also pick up the machine name only? If so, what version of ArcGIS Products are installed?
