RE: VNC server stops responding after a few days

2011-11-16 Thread Long, Phillip GOSS
James:

Is your static IP address in the range of the router's DHCP 
addresses?  That won't work, because the computer, knowing that it 
has a static IP, won't request a lease renewal, and after some 
maximum amount of time, the DHCP server will try to force one.  
What will happen in this case depends greatly on the software and 
OS the computer is running, and on the behavior of the router.  I'm 
not a network guy, but I do know that unless your router is more 
sophisticated than the average small-office router, static IP 
addresses *MUST* be outside any range of DHCP addresses of your 
router.

Thx, Phil Long

The computer will work in other ways but not with VNC. It's set as 
static IP, so the router should be giving the same IP after the lease 
times out.

 Hi everyone,

 We've got a problem with RealVNC server which stops working after a
few
 days. A computer reboot is required to get it to work again. The
error
 message upon connecting is: unable to connect to host. 2 computers do
 this on the regular and they have Windows XP installed. Is this a
known
 problem? Any idea what could be causing it?

 DNS lease timeout?

Hi Phil,

The DHCP addresses go from 100 to 253 while the computers running VNC 
have static IPs less than 100 (99, 98, and 97).
