Loads of problems here, none of them directly related to your problem...
1) Never hard code connection strings: use a config file (or at the very least a const string so it only needs to be entered in one place).
2) Connections, Commands, and so forth as scarce resources - you need to Dispose them properly when complete. A using block is the simplest way to do that.
3) Don't use a DataAdapter for a simple one line insert: it's very wasteful. Generate a stand-alone SqlCommand object and use that instead.
4) Never store passwords in clear text - it is a major security risk. There is some information on how to do it here: Password Storage: How to do it.[^]

Fix those, and your problem will probably vanish at the same time...
