That's really bizarre.
I personally don't think it sounds like a permissions issue IMO, usually in my experience those issues are encountered during the checkin process... e.g. trying to check into a folder with deny modify rights, it'll try and check it in then Vault return an error. Off the top of my head you can log into Inventor as a Document Consumer and it'll let you attempt to check something in, but then block it after the transaction is attempted when it does the permissions check.
If nothing that the other guys above suggested works, and you're 100% sure the logins are not different (it really does sound like that on face value), I'd do the following:
1. Add/Remove Programs > Change Vault Client, remove the CAD plugins, then put it back on.
2. Delete the local IPJ, get a new copy from Vault.
3. Login to both Inventor and Vault as the Administrator account, see if that works OK.
If it still doesn't work, see if you can narrow it down to a certain user or PC, or folder within Vault, try different combos of check outs from different folders using different users on different PCs.
Oh, corporate site, does that mean this is a replicated Vault environment?
If so, then you have the added bonus worry of folder ownership to contend with and look into. Although still, I'm pretty convinced if you try to check into a folder not owned by your site it still at least attempts the check-in.
But OK try the other stuff and report back 
Who set up all the lifecycle definitions & categories etc? Was that someone up at the main site?
If you can't get it working, and you don't have a reseller that you can bounce this to, could you do a screen print or even better a screen video showing the actual greyed out button in context with the rest of the CAD program. Might be able to spot something else from the overall picture.
Ah OK no probs, I now see your problem, trying to fix a problem on a Vault you didn't have any input into setting up! Nightmare 
Good luck!
Which versions of Vault and Inventor is the user working on?
Does this happen on 1 computer? on all? with one (specific) Vault user account? with all?
And, most of all, how is your file checked out (or rather: where from...)?
Is it checked out from the Vault client or from within Inventor?
When you have such a file checked out, and you cannot chack in, how does the "Vault explorer in Inventor" look like?
I think most of what you've mentioned has already been said/asked on the previous page, he's going to connect into the customers site today and report back with any news,
Hi Marshall,
Did you ever get this sorted?
I just had the exact same thing happen to me, exactly the same symptoms, I checked the file out from Vault Explorer -> opened the file in CAD logged in as the same user, now check-in is disabled/greyed out.
I know what the issue is with my setup, I hadn't finished setting it up right. Basically I didn't have the local workspace set correctly in the Vault Client.
Checking out from Vault Client sent the files & checkout to "C:\Users\Neil\Documents\Vault\Workspace\Drawings"
But I had the file open in CAD from the folder "C:\$WorkingFolder\Workspace\Drawings"
The Vault Client is sending the check-out to a different folder than the CAD application is opening them from. This can easily happen in an environment where the local workspace isn't enforced by admin. I just hadn't done that part yet as it's a test system I hadn't finished setting up, noticed this happen, then remembered this was something you'd previously brought up. It's a confusing situation to be in, and I guess nobody within the Vault team has designed a status symbol for this scenario. So from within CAD it all looks legit until you try and check in, which it then can't do.
Champion. I reckon that'll be it, even more so now that you mention there's some funky redirection going on. If the Vault Client is checking out to C:\ but then there's an OS level redirect pushing them to D:\, then the user opens from D:\, the files aren't opened from the same location as they were checked out to. That'll cause the checkin option to grey out. As verification, if the user does 'Open From Vault' from CAD, chances are it'll let him check-in and out without issue.
Side note: I've done a few installs where the some of the computers had low capacity on C, but I've just been annoyingly stubborn with the IT team and insisted that they stop being ridiculously tight and get the computers up to a decent standard. I won't let the integrity of my Vault builds be compromised because someone want's to save a few quid on a new hard drive! But that's just me, and sometimes it doesn't go down too well haha 
I think you mentioned you guys didn't do this build, is it not worth approaching them and telling them their Vault isn't looking solid, if that part isn't done right the chances are a few other essential things aren't done to best practice?
