Question : IP Security Camera cannot be accessed by some PC's

We have a D-Link DCS-5300G security camera.

It's on a simple small TCP/IP static network.  

It was functioning fine as a wireless device.  Then a couple PC's were unable to access the unit - IE couldn't load the page...not found.

The other PC's can access the unit via Internet Explorer just fine.  The IP is 192.168.53.65 and the IP on the client systems are 192.168.53.x

The clients that cannot access the unti CAN ping the IP address just fine and there are no other networking issues.  

I tried to wire it thinking it was an issue with the wireless aspect, but even wired- the symptoms remain.  

This should just work on evryone's system, but it doesn't.  Again, the client PC's (including my own) can access other network devices within our address range just fine.  They are fairly vanilla IBM workstations with Win XP Pro SP2.  

I added another Network security camera with no issues that works on everyon's client.  However, we'd like to use this D-Link as it has a wide angle lens.  

I don't even know what to check, which is why I'm posting here,  

Thanks in advance!

Answer : IP Security Camera cannot be accessed by some PC's

A couple of ideas.  Have you verified that there are no IP conflicts.  How if the camera getting its IP address?  DHCP/Static?  if you ARP the IP of the camera from a comptuer that can't access it, does it give back the MAC address of the camera?  You can do that by first pinging the IP and then typing

arp -a 192.168.53.65

Hope that helps.
