Добрый день всем. Пытаюсь настроить Outllok Anywhere. Публикуется внутрь через Nginx. Включена Basic авторизация.
Вот на этом этапе возникает ошибка:
Попытка проверки связи с конечной точкой RPC 6001 (Exchange Information Store) на сервере exch-dag.domain.local. Не удалось выполнить проверку связи с конечной точкой. Ошибка RPC вызвана процессом исполняемого модуля RPC. Ошибка 1818 CallCancelled Затраченное время: 31044 мс.

Добрый день уважаемые читатели, продолжаем наш с вами траблшутинг Active Directory в Windows Server 2012 R2, ранее я вам рассказывал, о таких ошибках как ошибка 1722 сервер RPC не доступен на контроллере домена и ошибку 14550 DfsSvc и netlogon 5781, все они не давали нормальной репликации базы данных и групповых политик в домене, что не есть хорошо, мы с ними разобрались, через какое то время при репликации, снова возникла новая ошибка, с текстом: 1818 удаленный вызов процедуры был отменен, давайте смотреть в чем дело и как это решается.
Причины ошибки 1818
Причинами, при которых у вас удаленный вызов процедуры был отменен, во время репликации Active Directory, могут выступать:
- Нестабильное сетевое соединение > я встречал случаи, что ошибка 1818, появлялась из-за, того что виртуальная машина с контроллером домена каждые 5 минут отваливалась. Проведите ее мониторинг по пингу и доступности, а лучше поставьте заббикс.
- Не правильно настроены DNS имена > об этом я уже писал в статьях про ошибки Active Directory и репликации KCC, ссылки выше. Я много раз встречал, что по неведомой мне причине, администраторы прописывали в настройках DNS сервера, адреса провайдера, а потом удивлялись почему не работает, запомните на контроллерах домена прописываем только локальные DNS сервера, а уже на самих локальных делайте форвардинг на провайдерские. Вот вам статья как настраивается форвардинг DNS запросов.
- Слетели права на папку SYSVOL > проверьте на работающем контроллере домена, какие права там выставлены и посмотрите их на сбойном.
- Проверьте не блокирует ли файрвол, нужные порты для службы Knowledge Consistency Checker (KCC)
Ошибку 1818, я получил при выполнении команды, проверяющей время последних репликаций контроллеров домена.
Исправляем ошибку 1818 удаленный вызов процедуры был отменен
И так в моем случае был не стабильный канал между контроллерами домена, и служба KCC, не успевала произвести репликацию, по установленному ей таймингу, но это исправимо. Нужно поправить параметр реестра Windows PC Replication Timeout (mins), оно по умолчанию 5 минут. Microsoft советует этот лимит увеличить до 45 минут. Открываем редактор реестра Windows Server 2012 R2 и переходим в ветку:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices NTDSParametertips
Создаем тут новую ключ, типа DWORD (32 бита) со значением RPC Replication Timeout (mins) и ставим ему значение 45.
После этого перезагружаете ваш контроллер домена и проверяете статус репликации Active Directory.

Question

Hi I have SBS 2011 (exchange 2010) and recently I installed IIS ARR to act as a web proxy. Everything works like charm except RPC over HTTP. I am getting this when I test via testexchangeconnectivity. it is similar to
this thread
Attempting to ping the MAPI Mail Store endpoint with identity: DC.Domain.local:6001.
The attempt to ping the endpoint failed.
Additional Details
An RPC error was thrown by the RPC Runtime process. Error 1818 CallCancelled
Elapsed Time: 32834 ms.
Since I am not that experienced I cannot benefit from the answer. Can you please help. When I open Web Server and search
• Check the RpcProxy ValidPorts
1. On the RPC proxy server, start Registry Editor (Regedit).
2. In the console tree, locate the following registry key: HKEY_LOCAL_MACHINESoftwareMicrosoftRpcRpcProxy
3. In the details pane, right-click the ValidPorts subkey, and then click Modify.
4. In Edit String, in the Value data box, type the following information
ExchangeServer :6001-6002; ExchangeServerFQDN :6001-6002; ExchangeServer :6004; ExchangeServerFQDN
:6004I dont have RpcProxy key. Do I need to create this key or I need to install Exchange server on IIS ARR machine that will route these kind of requests? In general is how to create RPC Proxy machine?

Hi,
We can try:
1. Take IIS backup using command «%windir%system32inetsrvappcmd.exe add backup «My Backup Name»»
2. Increase the allowed content-length value IIS Console—>Default Web Site—>Click on Request Filtering—>Click on Edit Feature Settings —Increased the Maximum allowed
length value to 1 GB.Thanks,

Ugh. We built a greenfield AD and Exchange 2010 environment a few months back for a large client. Outlook Anywhere isn’t working. Outlook clients just never connect, doesn’t seem to be an error or timeout.
This was a migration. Originally we had a cert mismatch for Outlook Anywhere so I’m fairly certain it never worked. We recently changed everyone’s SMTP domain suffix to match the webmail URL’s domain, so I expected that OA would start working. Now we have a snow day, lots of people at home, and it turns out it doesn’t work. Looks like there’s some sort of problem with proxied RPC connecting to OAB but I’m quite stumped as to how to fix this.
Autodiscover is good, OWA, ActiveSync, EWS all have been working for months.
We have 2 mailbox servers in a DAG, 1 mailbox server for public folders and journals, a 2-server CAS array. On the inside, we have NLB for the array. On the outside, we have a simply Netscaler LB VIP for the array that does nothing special, just a TCP 443 passthrough.
RCA shows this — it’s always about 33 seconds so I assume there’s a 30-second timeout here.
Attempting to ping RPC proxy webmail.5ssl.com. RPC Proxy was pinged
successfully.
Additional Details Elapsed Time: 201 ms.Attempting to ping the MAPI Mail Store endpoint with identity:
PFEXCAS.internal.domain.name.com:6001. The attempt to ping the endpoint
failed.
Additional Details An RPC error was thrown by the RPC Runtime process. Error 1818 CallCancelledElapsed Time: 33536 ms.
Now, both CAS servers are indeed listening on TCP 6001. PFEXCAS is the name of the NLB VIP.
This works for ports 6001, 6002, 6004, so that’s good
rpcping -t ncacn_http -s pfexcas.internal.domain.name.com -o RpcProxy=pfexcas.internal.domain.name.com -P » , , » -I » , , » -H 1 -u 10 -a connect -F 3 -v 3 -e 6004
This does not, it gives a 1722
rpcping -t ncacn_http -s pfexcas.internal.domain.name.com -o RpcProxy=webmail.5ssl.com -P » , , » -I » , , » -H 1 -u 10 -a connect -F 3 -v 3 -e 6004
Test-OutlookConnectivity -Protocol:Http -verbose works just fine on both servers, including the GetNewDSA and RFRI::GetReferral for the Address Book, those fail in our next test.
This is Ex2010, so HKEY_LOCAL_MACHINESOFTWAREMicrosoftRpcRpcProxyValidPorts_AutoConfig_Exchange has been checked and looks correct on both CAS servers
PFEXCAS:6001-6004;PFEXCAS.internal.domain.name:6001-6004;PFEXCAS01:6001-6004;PFEXCAS01.internal.domain.name:6001-6004;PFEXCAS02:6001-6004;PFEXCAS02.internal.domain.name:6001-6004;PFEXMB01:6001-6004;PFEXMB01.internal.domain.name:6001-6004;PFEXMB02:6001-6004;PFEXMB02.internal.domain.name:6001-6004;PFEXMB03:6001-6004;PFEXMB03.internal.domain.name:6001-6004
Running Test-OutlookConnectivity -RpcProxyTestType:Internal -RpcTestType:Server -verbose gives us this (results same/similar when run on either CAS server. So there’s something wrong with RPC proxying to the address book but hell if I can figure out what. Everything else in the environment seems to be working just fine, and this setup was configured quite closely to the original environment which had working OA.

Not sure if I have this RPCPing command correct but here goes… The following output is identical, with the exception of the ping time, when the command is issued from the CAS server itself or from a client machine connecting in over the Internet.
rpcping.exe -t ncacn_http -s mbx.internal.local -o RpcProxy=mail.external.com -P «username,INTERNAL,*» -H 2 -u 10 -a connect -F 3 -v 3 -E -b

As the ping was successful I have moved on to the endpoints as per ‘http://msexchangeteam.com/archive/2008/06/20/449053.aspx .
rpcping.exe -t ncacn_http -s mbx.internal.local -o RpcProxy=mail.external.com -P «username,INTERNAL,*» -H 2 -u 10 -a connect -F 3 -v 3 -e 6001

Okay so I have disabled Outlook Anywhere and waited for it to replicate the topology. I then re-enabled Outlook Anywhere and then waited for it to replicate again (MSExchange ADAccess 2080). Once it had replicated I re-ran the RPCPing…
rpcping.exe -t ncacn_http -s mbx.internal.local -o RpcProxy=mail.external.com -P «username,INTERNAL,*» -H 2 -u 10 -a connect -F 3 -v 3 -e 6001

As RPCPing Exception 1722 pointed to the RPC not being available (ref: http://support.microsoft.com/kb/831051) I checked the Application event log on the CAS and confirmed that I had neglected to wait for the RPC settings to be re-applied (MSExchange RPC
Over HTTP Autoconfig 3006).
Once the RPC/HTTP autoconfig event was logged I ran RPCCfg:
rpccfg /hd

I then tried another RPC Ping:
rpcping.exe -t ncacn_http -s mbx.internal.local -o RpcProxy=mail.external.com -P «username,INTERNAL,*» -H 2 -u 10 -a connect -F 3 -v 3 -E

As this succeeded I re-ran the RPCPing to the Store:
rpcping.exe -t ncacn_http -s mbx.internal.local -o RpcProxy=mail.external.com -P «username,INTERNAL,*» -H 2 -u 10 -a connect -F 3 -v 3 -e 6001
