What’s Causing that DFSR Change Storm?

[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 – here… Read more

Friday Mail Sack: Get Off My Lawn Edition

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-to-one certificate mappings LinkID… Read more

Friday Mail Sack: I Have No Idea What to Call This Edition

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 Cross-forest trusts and the Infrastructure Master DFSR file rename and… Read more

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 issues ILM Support Listing all GC DNS records AppLocker and MMC… Read more

WDS and DFSR: Love at First Sync

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, and all that other stuff that gets the OS installation… Read more

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 debug logging Understanding DFSR… Read more

Understanding DFSR debug logging (Part 21: File replication performance from throttling (uses debug severity 5))

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 as determining that slow replication has been… Read more

Understanding DFSR debug logging (Part 20: Skipped temporary and filtered files (uses debug severity 5))

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… Read more

Understanding DFSR debug logging (Part 19: File Blocked Inbound by a File Screen Filter Driver (uses debug severity 5))

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.   (filescreenupstream – Dfsr00008 –… Read more

Understanding DFSR debug logging (Part 18: LDAP queries failing due to network (uses debug severity 5))

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 called 2008x86SRV10 and 2008x64FSDC01 in the… Read more
