All, I've been using an Excel sheet that contains columns for all my electronic and network devices with information such as: MFG, vendor, date installed, serial number, MAC, IP, username, password, location, version, etc.

I have few hundred lines and try to keep up with everything I install/remote/test, etc.

I'm wondering how you guys deal with devices such as DVRs, where there may be multiple usernames, passwords?

I'm not fond of creating separate line for each one, as that could get messy. Would I copy all columns with the data?
Should I only duplicate serial number and sort that way?

Should I just bite the bullet and create MSAccess database?

Are there basic programs that would do what I'm looking for?

I use LastPass, but that's not really a good way to keep track of all the columns listed above.
