too many connections on NT4.0 SBS

By mike_m ·
Hi. HAve mixed NT4.0 SP6 SBS server, and NT4.0 SP6 clients. Quite often a client is refused access to a shared resource, with message "there are as many connection as this server can accept".
Actually I see no more than 5 open files, and even closing everything it takes about 10 minutes to clear resurces and grant access. How can I manage this problem, or can I determine exactly which resource is using too much resource, and how can I kill it immediately ?
Thank you. Mike

too many connections on NT4.0 SBS

Small Business Server has a limit to the total number of concurrent connections it will allow, and I think it depends on your licencing.
If you have a 5-client access version of SBS, then you only get 5 clients connected at one time.
You would need to upgrade the licencing information (SBS4.0 goes to 25 clients; SBS 4.5 goes to 50 users).
Or, upgrade to NT4Server (if you can still find a copy) or 2000 Server!

Now, something you can help with connectivity is:
net config server /autodisconnect: time_before_autodisconnect

Run this line on the SBS server to set the number of minutes until inactive client connections are dropped. Please read Technet article Q138365 on this one:

(please remove any spaces)

hope this helps

Ok Thank you. Server wasn't installed by myself and have little documentation of previous activity. At present don't feel like reinstalling everything. Hoe can I determine how many licenses I have granted? I changed time_before_disconnect to 2 minutes, but problem persists even with few connections. Also on server manager I see blue stations that are actually down, and "viewing only participating to domain" everybody is dimmed, even if actually participating (they are granted login to DOMAIN_NAME, and user profiles corresponds to the one stored on server). Something seems not ok. Also one client is always dimmed (domain and PP), but actually exists and works absolutely fine (login, file access, share etc.). It has been disconnected, renamed, riconnected, and renamed and remains dimmed (accepted, trusted,but dimmed). Can You help ? Thank you very much. Mike.

Well, there are a couple of possibilities here, but first, in order to tell how many licenses are actually installed for SBS, you need to open the SBS Management Console (should show at the top of the Start menu) and then click the About button on the main console page. This will bring up the page that shows you how many licenses are installed. If you have too few licenses to accommodate all the workstations that are connected at one time, you need to purchase an additional client license pack (they come in increments of 5). Another thing to check is the service pack levels. Are you on SBS 4.0 or 4.5? 4.0 had many problems, among which were problems with Exchange licensing which caused the symptoms you are experiencing. Unfortunately, if you're on 4.0 I'm not sure if you can still upgrade to 4.5 for free. SBS 4.5 seems to have fixed most of the licensing problems and there was originally a free upgrade available. However, now that SBS 2000 has been out for some time, I'm not sure if that free upgrade is still available - check Microsoft's SBS web site. If not, you're stuck because you can't buy an upgrade license from 4.0 to 2000, although you can buy a full license and then upgrade the system. If you're already on 4.5, make sure that you have installed Exchange SP4 as well as NT SP6a. The other thing to check is to be sure you don't have a shared resource with a connection limit set on it (on the Sharing tab). Hope this helps!
