About ADAM and VB web application

Hi,

i have a web application that use a VB component COM+ in Windows 2003
envoirment for connect to ADAM (IP NLB of 4 instance of 4 different server)
for do query about the values of 4 attribute.

I use a ADSI for connect to my LDAP and for logic that use my web
application every time that a use log in to my web a connect to LDAP start
for a query.

I have about 750 connect/sec on 6 different web server that point to my
application sever invoke a remote COM+ object on this server for connect to
ADAM and i have note that sometime application error occurred ("The server
is not operational") .

After sniffed a network traffic a note that this error is not returned by
ADAM because before a VB COM+ object try to connect a error show; if i try
to netstat -na i found more conenction to "TIMEWAIT" and i have verified
that every time that i try to connect a new socket was open so the nimber of
open socket end because there is some connection in ESTABLISHED a more in
"TIMEWAIT" that not recycle before that 240 sec (for default)

At the moment i modified a number of socket that Windows 2003 maybe open
(10000) e the time of time wait (30 sec.) but i consider it a workaround ;
exist a solution to my problem ? It's right share only one connection to
LDAP for all call ? It' s right for the COM+ state less ?

I check in the source code if evry time that can to open a session i closed
it and it's' ok.

How i resolve it , anybody have any idea ?

Thanks in advance
