Question :

I got this error “This file server will not allow any additional users to log on, please try again later” when I tried to access files that were on my network, but not on my Mac itself.

How can I fix this ?

Answer :

You can get this error when trying to connect to either another Mac or a Time Capsule in your network. The solution depends on the type of ‘server’ you are trying to connect to.

-A-

On a Mac running a normal (non-server) version of MacOSX, only 10 clients can be connected at the same time. If you get this error, despite the fact that you have less than 10 clients connected, try this :

– on the Mac you want to connect to, open the Terminal.app and type this command :

sudo defaults write /Library/Preferences/com.apple.AppleFileServer idleDisconnectOnOff -bool YES

– then press RETURN and you will be asked for your password

– type your password, press RETURN, quit the Terminal.app and you’re done (please note that the cursor will not move while typing your password in Terminal.app)

– whenever you want to undo (or reverse) this action, follow the same routine, but use this command :

sudo defaults write /Library/Preferences/com.apple.AppleFileServer idleDisconnectOnOff -bool NO

-B-

If you get this error message when connecting to a Mac and you need to have more than 10 clients connected, try this :

– upgrade the version of MacOSX you’re running (on the Mac you want to connect to) to the server-version of MacOSX, as OSX Server can handle an unlimited number of clients ; you can get the latest version of OSX Server in the Mac App Store

-C-

If you are trying to connect to a Time Capsule and you get this error message, the problem is something completely different. The Time Capsule can handle up to 50 clients at the same time, so chances of running into that limit in a regular household are low. But, the average internet provider has a limit of only 10 concurrent internet connections on it’s modem at the same time, so if you get this error when trying to connect to a Time Capsule, the 10 internet connections limit will probably be the cause. So try this :

– startup the AirPort Utility on your Mac

– click on the Time Capsule icon so the ‘info balloon’-window will open

– click on the “Edit”-button

– in the window that opens, click the “Network”-tab/button

– at “Router Mode:” select “DCHP and NAT”, so not “Off (Bridge Mode)”

– then click on the “Network Options…”-button

– in the window that opens, at “IPv4 DHCP Range:” select a range of IP-addresses that is different from your internet modem’s IP-range. So, if your internet modem’s IP-range is 192.168.1.xxx select an IP-range like “192.168.2.2 to 200” and click the “Save”-button

– in the next window, click the “Update”-button

– then, back in the ‘info balloon’-window of your Time Capsule, at “status” you will get “Double NAT” with an error mark (yellow dot) next to it… so, click on the “Double NAT”-text and in the pulldown-menu that opens, select “Ignore”

…that’s it !

Enjoy !
