Xnest Font Server setting

Hi, 

I am trying to connect to XServer using Xnest as follows : 

> Xnest :1 -kb -terminate -name -query <X_SERVER_IP> -geometry 1280x969 -fp tcp/<FONT_SERVER_IP>:7100 

but I can only see a blank window which vanishes within a fraction of a second. 
The error I see is : "could not open default font 'fixed'". 

Now, if I use, 

> Xnest :1 -kb -terminate -name -query <X_SERVER_IP> 
-geometry 1280x969 -fp 
/usr/X11R6/lib/X11/fonts/cursor/,/usr/X11R6/lib/X11/fonts/arkpandora,/usr/X11R6/lib/X11/fonts/TTF,/usr/X11R6/lib/X11/fonts/misc 

then I can successfully connect to X and can see Xnext login window. 

Now, if I run the first command again then this time it works fine without any error. 

Is there any reason why it did not work if I tried only FONT_SERVER_IP:7100 before specifying all the font paths and it worked after specifying font paths? Does this have anything to do with caching? 

Regards, 
Girish
