F15 Xfce Problem

[vx2015]

I installed F15 Xfce and now I keep getting the following message after i login:

Could not loop up internet address for WXZ. This will prevent Xfce from operating correctly. It may be possible to correct the problem by adding WXZ to the /etc/hosts on your system.

I tried a fresh install just to see if I did something wrong but I keep getting the same message.
I'm new at this, how would i go about changing the name? (in detail if possible)

I am also on F15, just installed Xfce and also get the exact same message when logging into Xfce (although WXZ=myhostname.mydomainname on my system). Looking for reason/solution to error.

Add yourhostname.yourdomain to /etc/hosts like:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 yourhostname.yourdomain
and Xfce will stop complaining.

That fixed it right up, thanks so much

I found the answer at another site but I don't know if I did it right. The problem is gone now. Here's what I did:

All I did was to change "localhost":

127.0.0.1 localhost.localdomain localhost

with "WXZ":

127.0.0.1 WXZ.localdomain WXZ

Then I saved it. The message is gone now after I log in. If I did it wrong let me know? Thanks for the responding.
