comment Troubleshooting High TCP Retransmit Rate
A standard MTU on a LAN is 1500. If you subtract 28 from that, you should be able to ping a remote host with ping -f -l 1472 n.n.n.n with no timeouts or DF warnings. I have to say that "hundreds of clients" sharing a 1Mbit down/512 kbps up connection I would expect to see a lot of retransmits though.

comment Troubleshooting High TCP Retransmit Rate
Forgetting the Google ping test, what is the MTU of the link to the hosts where you are experiencing retransmits? Also, can you provide the output of the command: netsh interface tcp show global

What version of tcpip.sys do you have on the client (and target host if Windows)?

comment How to locate the cause of a excessive memory in ms sql
The "server crashes"? Sounds like you aren't limiting the maximum memory available to SQL server. You also need to specify if you are running x86 or x84 SQL/Windows, and the total amount of system memory.

The stale ntfrs member and subscriber references should be removed during metadata cleanup. If not, you would need to manually delete them.

Many VB6 apps should work on 2012. It is possible that you may need to select a compatibility mode.

comment Search AD for empty sAMAccountName & userPrincipalName
Are you really expecting to find a user account with no samAccountName? That should not occur, and the system will not allow a user account to have an empty samAccountName if you try to clear it.
