Opening a program as a different user (with /savecred) fails

Question

What I'm trying to do is run a second instance (my personal account) of dropbox.

I have a second user account setup, Dropbox installed, the Dropbox folder on the second acct shared properly. Everything works exactly as expected if I launch the second instance using:

C:\Windows\System32\runas.exe /user:*[UserName]* *[DropboxLocation]*

But doesn't work when I try to launch using:

C:\Windows\System32\runas.exe /savecred /user:*[UserName]* *[DropboxLocation]*

I launched it using CMD and got the following Error Message:

RUNAS ERROR: Unable to run - *[DropboxLocation]*
1311: There are currently no logon servers available to service the logon request.

Note: FYI, I have already verified that the first line works in the command prompt without issue.

What I'm trying to do is save the credentials so I can move the shortcut to the startup folder, making it launch automatically when I login in to my primary account.

How do I go about fixing this issue and I'm correct in assuming that I should be able to launch an application as a different user on startup without having to enter the password every time (ie. this is the first time I have tried this in Windows 7).

Note: One potential cause of the issue is that the primary acct exists on a different domain than the secondary acct. I tried both the 'username@domain' and 'domain\username' forms in the 'runas' but yielded the same results (works without, but fails with '/savecred'). The primary acct uses a different domain, the secondary acct uses the computer name as the domain (ie. it's local).

Update: I'm running Windows 7 Professional SP1

From C:\> runas /?:

/savecred: to use credentials previously saved by the user.

This option is not available on Windows 7 Home or Windows 7 Starter Editions and will be ignored.

If you are not running a Home or Starter edition of Windows 7 please update your question to provide more details on your version and network setup.

Additionally, /savecred is ONLY for the user who ran the Runas /Savecred. So if you use Savecred, and give the password, you won't have to enter it again, but other users would have to repeat the /savecred, and enter the password, to have the credentials saved for their use.

You can see which credentials are cached in the Windows Credential Manager (Control Panel>User Accounts>Credential Manager)
