Hi all,
I have installed the ArcGIS Server 10.2.1 on Windows 7 without problem.
Next I tried install the web adaptor 10.2.1 on windows server 2003 R2 SP2 32 bits using the installer provided by ESRI but I got an error that I solved it by using line command install options:
msiexec /I D:\SetupFiles\setup.msi WEBSITE_ID=1 VDIRNAME=serviciosgis /qb
The installation process finished succesfully. Next I loaded the web adaptor page and I selected "Config ArcServer" and then I got the following error:
"HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable"
As additional information these servers are inside of a LAN which an proxy is configured.
I hope someone could help me. Thanks in advance.
