At a client site, Was called in because one user lost connectivity to the internet but not the LAN. I had him open up the TCP/IP properties and had him change the IP address from 60 to 49. After clicking OK, it reconnected to the internet.
We have a windows 2003 server (1) that is a file server, DNS server, print server, Domain controller (active directory). We also have a SonicWall TZ 200 router which is setup to provide DHCP. It was configured as of last week with .10-.15 as the IP range to give out. BUT all the PCs and the one server had static IPs in the .55-.60 range. I know that the router has mappings to allow someone on the outside to RDP with an IP address and a port number. the port number is configured in the SonicWall to correspond to a specific users PC so that they can remote in to their PCs.
the network has been experiencing of late, say the last few months connectivity problems. where they have to either reboot the server and/or router.
What could be misconfigured? There has to be a misconfiguration either in the server's configuration and/or the routers.
The server is also showing the following events in the event view for the DNS:
2, 6702, 4004, 4015.
Thanks in advance for the assistance.
