WAAS and dfs

Hi,
is there anybody firm in configuring WAAS with Microsoft dfs?
We have two WAE managed by Cantral Manager. Under File Services > Prepositions we want to configure dfs.
Can we configure a specific domain like xxx.yyy instead of a specific file server address?
Best regards

As a follow up to this questions. The customer currently has large file servers in their remote branches. They manually copy what files they need from one branch to another. I am planning on recommending a 274 appliance in this case due to the low number of users they have at each site. I have a couple questions though:
1. Cisco does not publish how many peers the 274 will support. Will this small of a box only work in a point to point configuration? What about customers that have any to any connectivity requirements over an MPLS WAN?
2. The 274/474 only support up to 35GB of HD space for the VB. If we were only to run Windows 2008 Core Server, would that much space be adequate for an AD/DHCP/DNS/Print Server in most cases even after updates? Do you have any idea on the storage requirements for MS 2008 servers on a virtual blade? Will 1GB be enough?
These are small sites and I don't want to undersize them from a VB or site to site standpoint.
What do you recommend?

  • BSOD on Server 2012 running dfs namespace and dfs replication roles with deduplication

    Hello,
    I have recently setup 2 dfsn & dfsr servers, both 2012 one physical the other virtual.
    The idea is to have one server as primary and the other as a failover \ DR.
    The primary server is virtual and connects via mpio \ iscsi to a dell san, using the provided dell DSM Drivers.
    The secondary server is physical with local disk for storage.
    I copy files to a namespace setup to always prefer the primary server, these files are then replicated across to the secondary.
    I have also turned on deduplication on both servers to get the most out of the available storage.
    This has been working well for 6 months or so, there have however been 2-3 occasions where the primary virtual server has crashed and blue screened causing the DFSR database to undergo a full consistency check.
    The bug check errors i have managed to extract from the Memory.dmp and mini dump are as follows:
    *                        Bugcheck Analysis                                   
    REFERENCE_BY_POINTER (18)
    Arguments:
    Arg1: 0000000000000000, Object type of the object whose reference count is being lowered
    Arg2: fffffa80379a3070, Object whose reference count is being lowered
    Arg3: 0000000000000002, Reserved
    Arg4: ffffffffffffffff, Reserved
        The reference count of an object is illegal for the current state of the object.
        Each time a driver uses a pointer to an object the driver calls a kernel routine
        to increment the reference count of the object. When the driver is done with the
        pointer the driver calls another kernel routine to decrement the reference count.
        Drivers must match calls to the increment and decrement routines. This bugcheck
        can occur because an object's reference count goes to zero while there are still
        open handles to the object, in which case the fourth parameter indicates the number
        of opened handles. It may also occur when the object?s reference count drops below zero
        whether or not there are open handles to the object, and in that case the fourth parameter
        contains the actual value of the pointer references count.

    I have searched for others having a similar problem but have not managed to find much.
    The memory dump at the time of the crash does seem to hint at a problem with DFSR.exe.
    The setup seems to be running fine again now and is going through its consistency checks, it is just a major inconvenience and will only get worse as the DFS becomes busier and approaches capacity.
    The plan was to put this setup into production however with the unpredictability of blue screen reboots I cannot see this happening until I can find a fix or work around.
    I have yet to see this problem occur on the other (physical) server, this is pretty much identical in configuration apart from its storage access.
    My thoughts are a possible bug in the DFSR component or a bug in the DSM Drivers used for the iSCSI SAN connection or maybe a combination of the two.
    Any help, thoughts or suggestions greatly appreciated
    Thanks

  • WAAS and IP SLA operation

    we are currently using the IP SLA udp jitter measurement to monitor our voice paths accross the WAN. If we implement a partial WAAS across the same WAN the voice traffic will be acellerated but not the IP SLA jitter measurement. Does this mean that when WAAS is implemented IP SLA is limited in its use?

    Hi Steve,
    The answer to your question depends on 1) how you deploy WAAS and 2) how you use IP SLA.  If you deploy WAAS using WCCP for interception, UDP traffic will never be intercepted.  If the WAAS device is deployed inline, all traffic flows through the WAAS device, so an IP SLA probe using UDP will be subject to WAAS pass-through handling behavior.
    What are you trying to measure with regards to WAAS?

  • WAAS and Juniper Netscreen Interoperability

    I've been doing a dig on historical posts relating to WAAS deployed through firewalls.
    I am working on a deployment with Juniper Netscreens & ASA5520 sitting between WAE's. IP connectivity is fine. I can ssh to remote device etc. but users cannot login (XP). The login scripts calls upon CIFS etc and I suspect this is being broken through the fw's.
    When I disable WAAS for this flow - it all works fine i.e. users can login and access full set of corporate resources. I suspect the firewalls but would appreciate any leads..
    thanks
    Ajaz

    Hi Ajaz,
    WAAS adds TCP Option 0x21 and increments TCP packet sequence number during TCP handshake. FW needs to be configured to allow
    these changes.
    On the latest PIX/ASA a new command "ip inspect waas" has been added to allow above changes by wae. You might want to check
    Netscreen config guide on command to disable TCP sequence number checking.
    If SSH to Servers is working fine then it might not be FW dropping packets. However to confirm it might be best to use
    tcpdump/tethereal on both WAEs and to sniff the traffic on whether its being dropped along the path by the FW.
    Few questions:
    - Whats the version running on WAEs?
    - Is it only CIFS traffic which is affected? Try disabling CIFS AO if its enabled and then test.
    Hope this helps,
    Best Regards,
    Rahul Vavale

  • WAAS and TACACS

    We are trying to get our WAAS environment to authenticate against TACACS and then fall over to local if TACACS is unavailable. For engineer logins everything is working as expected. However we are seeing several thousand failures against the TACACS server from a username of "CMS". This user is not configured in the CM or in TACACS. So we log the failed login and CMS logs into the WAE due to the failover to local mechanism. Looking at packet captures, and debugging aaa on the WAE's it is definitely a CMS user that logs in but shows 127.0.0.1 as its "from" host. I am fairly confident this is automation within the WAE syncing with the CM or vice versa. Does anyone know how to get WAAS and TACACS to work together without a mass amount of login failures? Is there a way this CMS user can be cloned/duplicated on the tacacs server? What is the password for this automation user?
    Thanks in advance.

    Hi Stan,
    WAE can authenticate against TACACS, RADIUS and Central Manager (Local) at any time depending on your configuration.
    There are couple of things to keep in mind while configuring TACACS on WAE, on both sides - TACACS adn WAE CM.
    On TACACS side:
    1. Please make sure to create right username.
    2. Please make sure to verify if you are using ASCII password authentication.
    3. Try to use less than 15 letters - Alphanumeric TACACS password.
    4. Please provide right user level / group level persmissions. This is somewhere under user account properties. Please also make sure to select right user password under user properties.
    5. Verify if this user needs level 15 (admin equivalent account).
    On WAE CM side:
    1. Please make sure to select right authentication method as primary and secondary.
    2. Please make sure to enable the check box for authentication methods.
    You can verify the failure / successful log events on TACACS server in order to find out if the user is atleast trying to authenticate against TACACS.
    I am sure you have looked at this link to find out all the required steps: Configuring TACACS+ Server Settings
    Hope this helps.
    Regards.

  • WAAS and Symantec Vertitas Volume Replicator

    Hi,
    We are forwarding Symantec replication traffic via our WAAS infrastructure over a 20Mb WAN link. The CM appears to register the traffic but does not optimize it at all. Has anyone had any experience with WAAS and Symantec Veritas Volume Replicator (VVR) 4.3?

    I tested with VVR in the lab. VVR default uses UDP and using the nerd knob in the GUI did not force VVR to start using TCP. To get VVR to use TCP, I had to input these commands:
    vrport data 1999-1999
    vrport heartbeat 2000-2000
    or use what ever ports you want to use. The previous answer was asking if you were seeing TCP sessions in the WAE's. This can be seen by telneting to the WAE and issueing a "show tfo connection summary". Can you post the output of that command?

  • WAAS and 512 Deployment

    Attach is the Visio as well as config for the India site. The Visio has 2 tabs (POC-WAAS and Proposed-WAAS). The POC (Proof of Concept) tab does not have the spare 3660 installed yet but I plan to do that soon. The "Proposed WAAS" is where we would want to be. However, my question will most likely address POC tab with the preparation to move to the Proposed tab.
    Current assumptions:
    Since we have a Manager in India, we will be getting another Manager in Calif, If so, I would like to setup a Primary/Standby deployment for redundancy.
    Questions:
    1. For Calif Primary WAE, the visio shows a Management interface but do I need a management interface or is it better to go with a standby interface instead as well as use MHSRP?
    2. Since we have a high speed link (4 Mb Internet for VPN in POC but 10mb WAN for proposed), should we tune the buffers to the max? If so how?
    3. Is this a recommend design for California? for India?
    4. Is my configs a recommend configs for California 3660 in POC? If so, what do I need to change in 3825 in Proposed?

    Zach
    After reading the SRND, I believe the best design is to move the 512 to the Cores. Please see the updated Visio and planned configs. Here's my updated requirements:
    1. Calif is hub
    2. All traffic to India (10.2/10.26) should go through the VPN tunnel through (ASA5520)
    3. All traffic to 10.3 and 10.5 should go through WAN via (R-Voice2)
    4. Latency to India is btwn 280 to 340msec and BW is 2mb. Do I also need to be concern with the BDP, L2 redirect(forwarding), and Mask assignments?
    TIA

  • FRS and DFS-R

    Hello There,
    We have a following FRS registry entry on Win 2003 DCs
    HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Internet
    Ports: REG_MULTI_SZ: 5101-5200
    PortsInternetAvailable: REG_SZ: Y
    UseInternetPorts: REG_SZ: Y
    We are migrating from Win 2003 to Win 2012 R2 and have configured the above registry and the following,  on win 2012 R2 DCs.   
    DFSRDIAG STATICRPC /port:5100
    Will the FRS and DFS-R conflict for port?. 

    Hi,
    From the description they will not conflict for ports.
    However if there is no Windows 2003 systems in your environment now, FRS is not needed anymore. By default from Windows 2008 R2, AD will also be replicated via DFSR instead of FRS.
    In Windows Server 2012 R2, Windows Server 2012, and Windows Server 2008 R2, FRS can be used only to replicate the SYSVOL folder on domain controllers in domains that use the Windows Server 2003 or Windows 2000 domain functional levels.

  • In-place Upgrade Server 2012 to R2 running DFS-N and DFS-R roles

    Hello, 
    I have 2 servers running DFS-R and DFS-N running Windows Server 2012. I am planning to do an in-place upgrade to 2012 R2. Is this supported?
    Rgds,
    Irfan
    Irfan Goolab SALES ENGINEER (Microsoft UC) MCP, MCSA, MCTS, MCITP, MCT

    Hi Irfan,
    Yes, you can upgrade Windows Server 2012 to 2012 R2 to deploy a later version of DFSR. DFSR must be recreated for that server and perhaps for the entire Replication Group depending on the server’s place in data origination.
    For more detailed information, please refer to the articles below:

  • Multiple Forest DNS queries, and DFS

    Setup:
    2 physical servers hosting several virtual machines with 3 forests (domains) and 3 subnets.  The physical server has 4 NICs, each forest/subnets has its own dedicated NIC via virtual switch (so 1 NIC is empty).  Each NIC connects to a switch to
    allow workstations and other devices to connect to their proper forest/subnet directly.  These switches then connect to the sonicwall (firewall/router) in an individual port.  Each port has proper subnet defined in it.
    The 3 forests are c.com, l.lan, and w.web named.  c.com and l.lan use a 10.x.x.x/255.255.0.0 subnet.  w.web uses 192.168.x.x/255.255.0.0 subnet.  There are no trusts setup.
    I can ping from one forest/subnet to the other using IP address without issue so the IP routes are fine.  I can ping via FQDN without issue if I setup a forwarder, conditional forwarder, or stub zone.  Sometimes using just the forwarder, FQDN does
    NOT resolve.  Conditional and Stub seems to resolve always. 
    I can get c.com and w.web to resolve single-name (host name) addresses, but at the moment (transitioning) they are on the same subnet.  From some research, I can use single-name resolution if I setup a GlobalNameZone as well, which I might need to do.
    So my question is which is best practice and most reliable way to setup these different forests and subnets to perform DNS resolution?  I tried forwarders, but it wasn't always reliable.  I suspected caching as an issue, but after a flush, a FQDN
    would sometimes resolve and sometimes not.  Conditional and Stub seem to work okay, but I'm not sure about what's best.
    I've spent most of the day researching this, and nothing was every really definitive and sometimes even contradictory.  Previously the DNS Forwarders worked fine for us, but that was on the same subnet.  Differing subnets seems to break the internal-to-internal
    forwarding.
    Additionally the w.web domain has a domain level DFS.  Neither of the other forests can access it via the
    \\w.web\data address.  Though they can access it if I point them directly to the server hosting the DFS namespace.

    Windows Server doesn't work well with DNS Search Suffixes defined in DHCP scopes from what I read.

    Details how to set it up on Windows Server DHCP
    http://social.technet.microsoft.com/Forums/en-US/2eed4d4f-8d1b-4989-ac49-d95e08b7d54a/dhcp-dns-suffix-search-list-supported?forum=winserverNIS
    Details how Windows Server does not support it though.
    http://technet.microsoft.com/en-us/library/bb847901(v=exchg.150).aspx
    Details how to use Group Policy to deploy it.
    How I fixed this:
    1) Open Group Policy for the domain.
    2) Edit the "Default Domain Policy" to include DNS Suffix search for current domain and all other domains.
    3) Set normal forwarders on domain's DNS servers.
    4) Repeat on all domain.
    This partially fixed my problem.  Things were resolving more reliably, but there would be a failure once in a while as well.  I corrected this by adding a conditional forwarder along with the normal forwarder.
    Now I get full resolution of all items.  Additionally, I do not have to use the FQDN for my machines.  Just hostname resolves just fine.  HOWEVER I would suggest to anyone setting up machines to use FQDN where possible, don't be lazy. 
    This means I will not have to setup a GlobalName zone either.  Though I may do it for the experience.
    Another problem though is this only works on Windows machines.  Mobile phones (such as Android and iPhone) and other such devices will not know about the DNS Suffix search.  Fortunately most of those devices required the internet FQDN for services
    to work anyway, and when behind the firewall via WiFi or like, they'll be able to still resolve the internet FQDN of devices since we're using a split-brain DNS for that domain.

  • Slow file browsing in MED-V / XP Mode with NAT and DFS

    Note, for the purposes of this question, this issue is with the Windows Virtual PC / XP Mode integration portion of MED-V so is not MED-V specific.
    We are in the process of deploying hundreds of MED-V instances to Windows 7 PCs to support legacy applications until they are replaced with versions that are compatible with Windows 7.  Due to security concerns and our network infrastructure configuration,
    we are required to use "Shared Networking (NAT)" mode for the Windows XP virtual machines.  Our network drives are mapped to DFS shares.  Depending on the site and drive mappings of a user, when opening or saving a file in an application,
    it can take several minutes to browse to the target directory, even if it's not on a DFS share.  Occasionally, it takes so long that the RemoteApp window hangs and disappears, even though the application is still running in the Windows XP VM.
    Running network traces in the VM, I can see that Windows XP tries to "ping" all of the DFS targets whenever the network drives are enumerated, such as when clicking on My Computer.  It waits for responses, then eventually times out. 
    From what I understand, this is the way that Windows XP determines which DFS target link is the fastest.  Unfortunately, since vpc.exe does not run with admin rights in Windows 7, ICMP (ping sends ICMP ECHO REQUESTS) is blocked by the NAT
    between the VM and the Windows 7 host.  (This is why you cannot ping other PCs on the network from within the Windows XP VM when using NAT.)  Therefore, the long wait times happen while XP waits for the replies that never come.
    To verify that this is indeed the problem, I started vpc.exe with admin rights, then started the MED-V Workspace.  I could ping other computers now from within XP and browsing took seconds instead of minutes.  However, our users will not have admin
    rights in Windows 7 so this is not an option for them.  I also tested in bridged mode instead of Shared Networking mode with the same positive results.  However, this is also not an option in our environment.
    Any solutions or recommendations will be greatly appreciated.
    Thank you in advance,
    Victor S.

  • WAAS and WCCP - looping packet detected

    Hi,
    Has anyone ran into this senario before. Before anyone answers with "move your WAE off the user subnet", it already has been.
    I have wccp 61 redirect in on the user subnet (gig0/0.83 of a dot1q trunk). The WAE is on gig0/1. Before I apply wccp62 to the serial link, I attempt to telnet from a user pc to the router (same subnet, clients default gateway), and the telnet fails. I get a "looping packet detected" on the router console. It shows the source of the packet as the router (wccp router id actually), and the destination ip of the WAE, but the packet came in gig0/1 (interface connected to wae). Obviously the WAE returned the packet to the router (with the original GRE headers, (router as source)). I thought WCCP would understand this as "don't redirect this traffic to me anymore", but the router, actually tries to route it back down gig0/1 and then sees it as a looping packet. I believe the WAE is returning the encapsulated packet to the router to indicate it doesn't want the flow, and the router is attempting to route the GRE packet, instead of realizing it should remove the GRE header and route the internal packet. Router is IOS 12.4(12) as recommended by my Cisco engineer. 2821 router.
    For kicks, I continue the WCCP setup on the datatcenter side. As expected, it doesn't work. When I apply the WCCP to the datacenter router (only redirecting lab subnet), the entire lab subnet is unreachable via TCP (but icmp still works as expected).
    The WCCP configuration isn't very complex, I can't believe its something I'm doing. I think its a code issue.
    Any advise?

    no "out" anywhere. The LAB router has a WAE list to only allow redirect to the lab WAE. I don't even need the 62 in on the WAN side, just applying 61 in on the LAN side breaks telnet to the router.

  • Microsoft Office and DFS namespace

    Hey guys
    We recently switch our folder redirection to a DFS server and now we have users experiencing "Trying to Connect to domain.local
    and I don't think its an error more just a visual message but is there anything we can do to disable or fix the issue? We have Windows 7 Clients w/ Office 2010 and Windows 8 Clients w/ Office 2013 both experiencing it when the Click on "Open" or
    "Save in the application.

    Hi,
    I think it is caused that Office consider the \\domain.com\root\folder is a place like an internet location (which is normal to me that Office does not know about DFS) and I assume it is the default behavior of Office for displaying "connect to xxx"
    while opening or saving files from/to an internet location. 
    I confirmed with Office engineer about disabling it but there is no such option in Office. You could post a thread to Office forum for further information about it:

  • User Profile Disks and DFS replication

    We're looking to replace a single, heavily used 2003 TS server--for performance, feature, and capacity reasons.  Our users frequently have small amounts of data on their desktops/settings that we'd to persist between sessions, and they tend to have
    long-running sessions (disconnecting and reconnecting while traveling, but not logging off--keeping open apps in the meantime).
    The servers were originally purchased intending for 2008R2 SP1 remote desktops services, with lots of fast internal (RAID 5, 12x300GB 15K) storage.  We're considering the option of using 2012 (virtual sessions, not virtual desktops) so that we can scale
    out as we grow--and use the User Profile Disks.  
    Ideally, we'd like to maximize the usefulness of the purchased servers (and their internal storage), and not have to purchase additional hardware for shared storage--(iSCSI/External array that can be clustered).  We're wondering if it's possible to pair
    the User Profile Disks (UPD) with DFS replication (possibly over a dedicated NIC). Then, a user could log in to server X, connect to her local UPD (with the changes replicating to server Y's copy).  If she disconnected/reconnected, the RD connection broker
    would connect her to back to her existing session, and if she logs off and back on, she could connect to either server X or Y and it would all work.  For maintenance, we'd be able to drainstop one server via the connection broker, perform the maintenance,
    let DFS catch up, and then do the same on the second server.
    Would something like this be possible?  Or is it just asking for major problems?
