mappage des imprimantes via clients tse
concordance de pilotes sur clients et serveur
clients : verifier l’emplacement des pilotes d’impression utilisés par le système, aller dans le registre vérifier la clé :
- Système 64 Bits :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows x64\Drivers\Version-3\ - Système 32 Bits :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows NT x86\Drivers\Version-3\
Il suffit alors de copier les fichiers sur le serveur TSE et de les importer via les options du serveur d’impression.

Perfmon Counters To Profile Memory Leak
Virtual Bytes: The current size, in bytes, of the virtual address space (VAS) for this process
Each time an application is run in an operating system (OS), the OS creates a new process and a new VAS for this process. Process memory is VAS memory, not physical memory. Physical memory is used by the OS to map values from file bytes to VAS addresses.
Private Bytes: is the current size, in bytes, of memory that this process has allocated that cannot be shared with other processes. Private Bytes represents the amount of private virtual memory a process has allocated and is the value that will rise of a process exhibiting a memory leak bug
Memory Leak Presence
If virtual bytes and private bytes rise and stay latched on to their highs then memory leak is present

dnscmd forwarders
To configure a DNS server to use forwarders using the Command Prompt:
1. Open the Command Prompt window with elevated permissions (Run as Administrator).
2. If you want to add the same DNS forwarders used in my previous example, in the Command Prompt window type the following command:
dnscmd <DNS_server_name_or_IP>/ResetForwarders 8.8.8.8 8.8.4.4 /timeout 3 /noslave
Some Final Notes:
- Separate the DNS IP addresses by a space.
- You cannot add individual entries one after the other, you must add all forwarders at the same time in one command. But you can add or change existing entries from DNS Manager.
- The /timeout switch specifies the amount of time that your DNS server waits for the forwarder to respond.
- The /slave switch indicates that the DNS server will not attempt to perform its own iterative queries if the forwarder fails to resolve the query.
- The /noslave switch means that the DNS server will use its root hints file if no forwarders are available to resolve the query.
