So, for a little background, about 7 months ago I bought a new laptop. Previously, all I had was a desktop. Both have Windows XP. I managed to get them networked without too much trouble, that includes dealing with ZoneAlarm. By networked, I mean, both connect wirelessly to a router, and I had file/printer sharing enabled. I keep a few folders on the desktop shared to the network and the printer is connected to the desktop as well.
All was well until just a few weeks ago. One day I attempt to access a shared folder, and I get an error about permissions. As far as I know, nothing changed. I could see the other computer on the network. I could even see all the shared folders, but I just couldn't access them. Also, I could still print without a problem.
I wasn't too worried about it, and figured I'd get around to fixing it eventually. Before I had the chance to do that, I went ahead and upgraded the laptop to Vista (had a free upgrade deal, figured I'd use it). Once Vista was installed, I discovered I couldn't print anymore; I'd get an error. I figured I'd just try re-installing it, maybe Vista needed to reinstall the drivers. No luck. I could see the printer on the network, but I couldn't add it to the laptop!
Anyhow, initially I thought it was a ZoneAlarm problem; it can be tricky sometimes. But after some searching around, someone finally gave me the obvious idea of turning off the firewall, and seeing what happens. So, I do, and I still get the same sort of errors. So, I know it has to be a Windows Networking issue, I just don't know what. And, being so new to Vista, I'm not real famililar with all the network stuff, so I don't even know how to go about changing or fixing some things.
Also, one odd thing I noticed -- or at least, it seems odd to me, but maybe not. But, I was checking on my ipconfig's on both machines and I realized that a) the Subnet masks were different (255.255.255.0 vs 255.255.255.252), and the default gateway on the laptop isn't the same as the default gateway on the desktop, although the DNS and DHCP servers agree between both (which is the same as the gateway on the laptop). I thought that seemed odd, but maybe I'm wrong.
I definitely need some help, and I'm at a loss to where to start. And, I want to emphasize that everything did work fine until recently, and I have no clue what may have sparked any changes to be made. The upgrade to Vista happened AFTER all that.
Thanks in advance!
