Error:Reverse lookup of address failed:(NW7.01ABAPTrailVersionInstallation)


Hi Experts,

There are lot of discussion threads around installation problems in SDN. I tried searching for my error and could not find relevant one. Please let me know if there is one.

I was trying to install SAP NetWeaver 7.01 SR1 SP3 ABAP Trial Version on Windows XP SP 2 (using VMware)

I struck at the step2: SAP System > DNS Domain Name

My system name is "".

I entered "" in the input field 'DNS Domain Name for SAP System' and was getting bellow error:

  • ERROR: Reverse lookup of address '-64.-88.-124.129' failed. **

I tried with following values but no use:




Even though we can skip this setting and continue installation, I think this setting is necessary for Web Dynpro development.

So, could any one help in finding right value for the 'DNS Domain Name for SAP System' input field?
