Hi,

We were having an issue with the Windows 10 upgrade MS recently released to WSUS server on our domain (the update would fail and the system appear not to download all the required files). To put a long story short the issue is in IIS and NOT WSUS per say. After some testing it turns out IIS was not serving the .esd file (this is the main update file) due to the mime type not being set. To rectify the issue:

under IIS Admin->WSUS Administration->Content-> Click on 'Mime Types'-> Add

File Mame Extention: = .esd

MIME type: application/vnd.ms-cab-compressed

If you have already tried to pull the W10 update you may need to clear your SoftwareDistribution Download Cache under the Windows Dir and clear out the hidden $WINDOWS.~BT

EDIT:

* The actual mime type for esd, according to http://www.filesuffix.com/en/extension/esd, is 'application/octet-stream'.

* You can test this issue by trying to download the esd file via FF,Chome,IE, Edge etc (WSUS will tell you where the file is located. In WSUS control panel right click on the update and go to 'File Information')

* The following is just to help people find this post:

A bitstream (or bit stream), also known as binary sequence, is a sequence of bits.

A bytestream is a sequence of bytes. Typically, each byte is an 8-bit quantity (octets), and so the term octet stream is sometimes used interchangeably. An octet may be encoded as a sequence of 8 bits in multiple different ways (see endianness) so there is no unique and direct translation between bytestreams and bitstreams.

Bitstreams and bytestreams are used extensively in telecommunications and computing. For example, synchronous bitstreams are carried by SONET, and Transmission Control Protocol transports an asynchronous bytestream.

Relationship between bitstreams and bytestreams[edit]

In practice, bitstreams are not used directly to encode bytestreams; a communication channel may use a signalling method that does not directly translate to bits (for instance, by transmitting signals of multiple frequencies) and typically also encodes other information such as framing and error correction together with its data.^{[citation needed]}

Examples[edit]

The term bitstream is frequently used to describe the configuration data to be loaded into a field-programmable gate array (FPGA). Although most FPGAs also support a byte-parallel loading method as well, this usage may have originated based on the common method of configuring the FPGA from a serial bit stream, typically from a serial PROM or flash memory chip. The detailed format of the bitstream for a particular FPGA is typically proprietary to the FPGA vendor.

In mathematics, several specific infinite sequences of bits have been studied for their mathematical properties; these include the Baum–Sweet sequence, Ehrenfeucht–Mycielski sequence, Fibonacci word, Kolakoski sequence, regular paperfolding sequence, Rudin–Shapiro sequence, and Thue–Morse sequence.

On most operating systems, including Unix-like and Windows, standard I/O libraries convert lower-level paged or buffered file access to a bytestream paradigm. In particular in Unix-like operating systems, each process has three standard streams, that are examples of unidirectional bytestreams. The Unix pipe mechanism provides bytestream communications between different processes.

Compression algorithms often code in bitstreams, as the 8 bits offered by a byte (the smallest addressable unit of memory) may be wasteful. Although typically implemented in low-level languages, some high-level languages such as Python^[1] and Java^[2] offer native interfaces for bitstream I/O.

One well-known example of a communication protocol which provides a byte-stream service to its clients is the Transmission Control Protocol (TCP) of the Internet protocol suite, which provides a bidirectional bytestream.

The Internet media type for an arbitrary bytestream is application/octet-stream. Other media types are defined for bytestreams in well-known formats.

Flow control[edit]

Often the contents of a bytestream are dynamically created, such as the data from the keyboard and other peripherals (/dev/tty), data from the pseudorandom number generator (/dev/urandom), etc. Free kids games spongebob squarepants.

In those cases, when the destination of a bytestream (the consumer) uses bytes faster than they can be generated, the system uses process synchronization to make the destination wait until the next byte is available. Vin number decoder.

When bytes are generated faster than the destination can use them, there are several techniques to deal with the situation:

• When the producer is a software algorithm, the system pauses the producer with the same process synchronization techniques
• When the producer supports flow control, the system only sends the ready signal when the consumer is ready for the next byte
• When the producer can't be paused—it is a keyboard or some hardware that doesn't support flow control—the system typically attempts to temporarily store the data until the consumer is ready for it, typically using a queue. Often the receiver can empty the buffer before it gets completely full. A producer that continues to produce data faster than it can be consumed, even after the buffer is full, leads to unwanted buffer overflow, packet loss, and network congestion.
