To check the version of your current driver please look at the properties of bxnd60a.sys. HP configured smaller MTU defaults in driver version 7.8.x.x, released on. Netsh interface ipv6 set subinterface 14 mtu=1500 store=persistent Netsh interface ipv6 set subinterface 13 mtu=1500 store=persistent Netsh interface ipv4 set subinterface 14 mtu=1500 store=persistent Netsh interface ipv4 set subinterface 13 mtu=1500 store=persistent Retry the PING command using larger values for the –l parameter until you either reach 1500 bytes or the command fails with the error: Packet needs to be fragmented but DF setįrom an admin-privileged CMD prompt, reset the MTU to the Ethernet default of 1500 bytes: An example here would be: ping–f –l 1472 hostname Where –f sets the Do Not Fragment bit –l sets the length of the ICMP packet IPv6 does not support the DF flag so the -4 argument can only be used with IPv4 and is not needed with -f. Don't modify the MTU value.Īn MTU value of 1514 however is likely caused by NIC driver and could cause problems If the underlying network infrastructure doesn't support jumbo frames (in which case the MTU value would be much bigger than 1514) You can also use the PING command to identify the largest unfragmented ICMP packet that a given computer can send to various remote computers on your network. ġ 50 4294967295 connected Loopback Pseudo-Interface connected Local Area Connection* 1connected iSCSI Bad System: Idx Met MTU State Namconnected Local Area Connection connected Local Area Connection connected Local Area Connection 3 If Jumbo Frame support is enabled, you'll see an even larger value like 9000 for MTU. This is a good command to run regardless of the hardware make and link speed you have. The NETSH command can be used to verify the current MTU settings used by IPv4 and IPv6. These types of network issues can be especially difficult to troubleshoot since MTU size is not typically a top-of-mind root cause. "The specified network name is no longer available"."The client cannot connect to the destination specified in the request".RPC operations, SMB connection, WinRM and other operations fails with error including but not limited to: Sending WMI commands to a remote server fails with error "RPC_S_SERVER_UNAVAILABLE" (The RPC server is unavailable).Creating a new 2 node failover cluster or adding a new node to an existing cluster fails with error "RPC_S_CALL_FAILED" (The remote procedure call failed).Server Manager and other administrative tools connect or manage remote computers.Cluster creation fails with RPC error 0x800706BE (where hex error 0圆BE = decimal error 17232 = symbolic error RPC_S_CALL_FAILED = friendly error "the remote procedure call failed" ).Event ID 30620 is logged in the File and Storage Services console.

Shared folders on NAS servers or remote Windows computers cannot be accessed, including admins shares like \%server%c$ or \%server%ipc$.Operational failures and errors caused by large MTU values include but are not limited to:

Regardless of what make and model NIC you have, we recommend that you run two simple NETSH and PING commands to verify that the network drivers connected to your networks are using MTU values compatible with the underlying network.

For Windows Server 2008 R2 this scenario only occurs if the NCU software was never installed or is removed. In some rare cases Windows Server 2008 R2 is also affected. Support cases involving the following NICS have been opened but other make and model NICs could be impacted.Īffected NIC driver versions for the HP-branded 1 GB Broadcom NICs start with version 7.4.X.X. Software developers have been known to configure > 1500 byte MTUs as was the case when several drivers for HP-branded Broadcom NICs slipped out the door with a default MTU of 1514 bytes. Larger MTU support (jumbo frames) may be configured when using overlay technologies like Hyper-V network virtualization and network operators must make sure that all the networking equipment like switches and routers can support larger MTUs.
