[This is another guest post from our pal Mark in Oz. Even if you don’t care about DFSR, I highly recommend this post; it teaches some very clever log analysis techniques, useful in a variety of troubleshooting scenarios – The Neditor] Hi there! It’s Mark Renoden – Premier Field Engineer in Sydney, Australia...

Hi folks, Ned here again. I know this is supposed to be the Friday Mail Sack but things got a little hectic and... ah heck, it doesn't need explaining, you're in IT. This week - with help from the ever-crotchety Jonathan Stephens - we talk about: Multiple WMI Filters LDAP MaxPoolThreads Many...

Hiya folks, Ned here with a slightly late Mail Sack coming your way. Today we discuss reading event logs, PowerShell, FSMO, DFSR, DFSN, GCs, virtualization, RDC, LDAP queries, DPM, SYSVOL migration, and Netmon. Do it. LogParser and Win2008 R2 security event logs DFS virtualization support...

Hello Earthlings, Ned here again with this week’s interesting conversations within Microsoft DS support. Today we talk DFSR, ILM, DFSN + VPNs, DNS, group expansion, Applocker, and friggin’ huge files. OG OG OG! DSGET -USER poor performance DFSR with massive files DFS and VPN...

Ned here again. Windows Server 2008 introduced a new way to roll out your computers called Windows Deployment Services (WDS). WDS replaces the old Remote Installation Services introduced a decade ago with Windows 2000. By leveraging WDS, you can create image-based deployments, script settings, multicast...

Ned again. As promised, here is the complete list of links for the recent 21-part DFSR Debug Log analysis series as well as downloadable versions of the series in Word 2007, Word 2003-97, XPS, and PDF formats. I have also included the debug logs I referenced as a separate ZIP file. Understanding DFSR...

In this final scenario we will see a file being replicated successfully, but where the replication appears to be very slow. A bandwidth throttle has been configured within the DFSR replication group schedule to restrict traffic to 128Kbps. This is useful in understanding how throttling works as well...

In this scenario we will see a pair of files being created on an upstream server. One of the files is marked with the TEMPORARY attribute and one has an extension of TMP which is being filtered by DFSR. This will show the common scenarios of files which do not appear to ever replicate for unknown reasons...

In this scenario we will see an attempted file replication. The downstream partner is running the File Server Resource Manager role with file screens configured and these screens are not matched to the DFSR file filters. The debug log has been set to severity 5 for deeper details than usual. (...

In this scenario we will see a DFSR server attempt to contact its DC through LDAP to read the current replication topology. LDAP lookups are being blocked by ‘firewall/network/DC down’ so there are no responses. ( ldapblocked - Dfsr00008 - 2008.log ) These are two Windows Server 2008 servers...

In this scenario we will see a file created on the upstream server and attempted replication with its downstream partner. RPC traffic is being blocked between the machines by an incorrectly configured firewall. This is a common scenario and basic understanding of firewalls, TCP/IP, ports, and RPC is...

In this scenario we will see a file modified and how that change is replicated between servers, specifically in regards to RDC similarity usage. The debug log has been set to severity 5 for deeper details than usual. This is useful to understand how efficient RDC is with a given type of file during a...

In this scenario we will see a new replication group and replicated folder created, where data has been pre-seeded (i.e. pre-staged) on both servers. This is a common scenario, where data has existed on a few servers and been kept in sync through other mechanisms than DFSR (such as robocopy ). It’s also...

In this scenario we will see file that is locked by an application, preventing replication from occurring. The upstream replicated folder will contain a file that does not yet exist on the downstream member. This is useful to understand as one of the most common troubleshooting areas in DFSR is in the...

In this scenario we will see a new Replication Group and Replicated Folder created. The upstream replicated folder will contain a few files that do not yet exist on the downstream member. This is useful to understand as one of the most common troubleshooting areas in DFSR is the actual configuration...

In this log we will see the DFSR service being started and follow the process of initialization up to the point where the service is fully functional. This is useful to understand in order to troubleshoot issues where problems within Active Directory, Network Communication, XML reading, or Registry reading...

In this scenario we will see a folder added and how that change is replicated between servers. This is useful to understand in order to troubleshoot issues where problems within the USN journal, the DFSR JET database, and the network (including RPC) are preventing replication from working correctly....

In this scenario we will see a file that has been changed on two servers in between replication convergence and how that conflict resolution is replicated between servers. This is useful to understand in order to troubleshoot issues (or perception of issues that are actually expected behavior) leading...

In this scenario we will see a file renamed and how that change is replicated between servers. This is useful to understand in order to troubleshoot issues where problems within the USN journal, the DFSR JET database, and the network (including RPC) are preventing replication from working correctly....

In this scenario we will see a file deleted and how that change is replicated between servers. This is useful to understand in order to troubleshoot issues where problems within the USN journal, the DFSR JET database, the staging folder structure, and the network (including RPC) are preventing replication...

In this scenario we will see a Microsoft Word 2007 file modified and how that change is replicated between servers. This is useful to understand in order to troubleshoot issues where problems within the USN journal, the DFSR JET database, the staging folder structure, and the network (including RPC)...

In this scenario we will see a Microsoft Word 2003 file modified using MS Word 2003 and how that change is replicated between servers. This is useful to understand in order to troubleshoot issues where problems within the USN journal, the DFSR JET database, the staging folder structure, and the network...

In this scenario we will see a file modified and how that change is replicated between servers. This is useful to understand in order to troubleshoot issues where problems within the USN journal, the DFSR JET database, the staging folder structure, and the network (including RPC) are preventing replication...

In this scenario we will see a small file copied into the replicated folder and how it is replicated between two servers. This is useful to understand in order to troubleshoot issues where problems within the USN journal, the DFSR JET database, the staging folder structure, and the network (including...

Ned here. Today's post is part three in the series, where begin examining specific scenarios in the debug logs. This post is a critical read as it explains how I will go through all the debug logs; without reviewing this section below the remaining logs will be more difficult to understand. Various...
