MongoDB on a Windows 7 machine: No connection could be made

Question

After I have started Mongo using mongod.exe on a Windows 7 machine, I tried to start the mongo shell that failed with the error:

Failed to connect to

Answer 1

I got the same error and fixed it with:

1) mkdir c:\data

2) cd data

3) mongod -dbpath .

4) Now in another command window I was able to connect from my client using the mongo command.
