Queu starvation (packet starvation)

If you have too many packet types being placed into the High queue, and even the Medium queue, traffic in the lower-priority Normal and Low queues ends up just sitting there. That's called queue starvation or packet starvation

VTP & DTP

Dynamic Trunking Protocol (DTP) sends the VTP domain name in a DTP packet. Therefore, if you have two ends of a link that belong to different VTP domains, the trunk does not come up if you use DTP. In this special case, you must configure the trunk mode as on or nonegotiate, on both sides, in order to allow the trunk to come up without DTP negotiation agreement.

Isa + ssl на нестандартный порт

По умолчанию в через ISA зайти по адресу вида https://somedomain.com:port где port - любой номер порта отличный от 443 (дефолтный для ssl).
Решению вопроса способствует VBS sсript

Dim root
Dim tpRanges
Dim newRange
Set root = CreateObject("FPC.Root")
Set tpRanges = root.GetContainingArray.ArrayPolicy.WebProxy.TunnelPortRanges
set newRange = tpRanges.AddRange("SSL 10000", 10000, 10000) tpRanges.Save

Вместо 10000 подставить нужный номер порта. После выполнения никаких сообщений не последует. Это нормально. При попытке повторного выполнения появится ошибка. Это тоже нормально.

После выполнения скрипта следует перезапустить службу ISA

Cannot start IPSEC service error. The system cannot find the file specified.

Description:
Suddenly you cannot logon to the domain from a server. You cannot ping it, even though the network card is connected to the network and functioning normally. You can ping to self from the server. No firewall blocks the connection. When looking through event viewer, you notice 2 errors were log; Event ID 7023 and Event ID 4292 (IPSec driver has entered Block mode). Both are related to IPSEC. You check the IPSEC services and found that you cannot start it. There’s “The system cannot find the file specified” error.

Resolution:
The problem occurs when there’s corrupted file in the policy store. The file may become corrupted if an interruption occurs when the policy being written to the disk. To solve it, please go to HKEY_LOKAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\IPSec\Policy\Local. Delete this subkey (if exist). After that, rebuild the new local policies store. To do that, click Start > Run > type regsvr32 polstore.dll. Try starting the IPSEC services again. All issue should work well now.
